Medusa enters the classroom only to find her student. She sits before him while looking him directly in the eyes. After some time, she speaks. I am Doctor Medusa, and I'll be your teacher in the school. Tell me about yourself.

I am Killua Hayabusa, I was born in the Land of Water to a family of assassins who despised me because of my dubious birth. I ran away once I came of age to the village Hidden in Mist where my skills were enhanced and put to use as a shinobi instead of an assassin, I then went off on my own journey to find the Hayabusa and learn about my mother. Killua was ready to learn, but his voice was monotone, lifeless.

 

[Priest]

Mdusa shakes her head and adjust her glasses. So a quick pop quiz. What can you tell me about Medical Ninjutsu and what it entails?

Mdusa shakes her head and adjust her glasses. So a quick pop quiz. What can you tell me about Medical Ninjutsu and what it entails?

Medical Ninjutsu is a specific sect or branch of Ninjutsu that revolves around healing, or control over one's body in the case of Self Empowerment. Medical Ninjutsu is also more than healing as most Med Ninja have extensive knowledge about herbs and poisons and the sorts. Killua said confidently

 

[Priest]

Medusa nods once again in acknowledgement. She would then begin to write on the white board, hoping the student would be taking notes.

Iryō-nin (Medical Ninja)​

A medical ninja is a ninja who has learned to make use of Ninjutsu and related skills to provide medical treatment to others. It also encompasses those that, using that knowledge, have enhanced their own combat abilities.

In Naruto Manga, fields like Kinjutsu, Fuuinjutsu and Poison techniques are deeply rooted into Medical Knowledge. Orochimaru is a fair example of how Medical Knowledge can be used to achieve greater power but he isn't the only one.

In Narutobase RPG, the medical ninja is capable of healing others and himself, cure poisonings, enhance his sealing knowledge and skill, develop his regenerative abilities and even learn to use poison techniques in combat.

Medical Ninjutsu is not unlike regular ninjutsu where you use your chakra to achieve effects that you would not be able to otherwise. Most Medical Ninjutsu techniques, however, are deeply rooted into Yang Release and make perfect use of Physical Energy.

Homework:

Students need to write a small text where they explain what chakra is, how it works and how the human body relates to chakra in narutoverse.

 

[Jᴀʏ]

Chakra is the result of combining your spiritual and your physical energies. Despite being usually made up of 50:50, chakra can also have a different ratio of both energies. Chakra is streamed through the user's chakra system where they go through the user's tenketsu to form techniques. In the Narutoverse Chakra is the basis of all jutsu, bar taijutsu. Killua said bluntly, reading through the course material and taking adequate notes he had no further questions.

 

[Priest]

Medusa pauses for a moment while looking at the student's work. She got to the taijutsu part and looks up.
Not all taijutsu. There are elemental taijutsu, special, enhanced/reinforced and KG taijutsu. We also have EIG. All this use chakra.

Medusa would switch to an electronic board and then opens a slide while explaining to the student all about troubleshooting.

Shindan (Diagnosis)​

A Medical Ninja needs to start somewhere and that somewhere is detecting the issue with your patient. Shindan or diagnosis is the first step in treatment; understanding the problem. With this skill you use your hands to carefully probe a patient for problems that you might not be able to see. Contact with the patient will initially be needed but with time becomes optional. Despite this, you'll always need a close proximity between your patient and your hands. This technique is preformed by approaching the patient and slowly running both hands over his or her body, using your chakra to examine the body and looking for signs of injury that may not be visible to the naked eye. It can detect any physical alteration to the body (internal or external wounds, lesions, tumors, fractures, diseases, etc) as well as its composition (glucose levels, iron levels, antibodies, etc ) and vital signs (blood pressure, heart rate, temperature, pain levels, breathing, oxygen saturation, etc).

A student of Medical Jutsu will require several minutes to assess all the details but a medical ninja will be able to do so in mere moments. To help less experienced ninjas or to aid in complex cases, direct contact is often used as well as chakra transmiting mediums such as water, wood, etc.

Mental injuries such as psycosis, depression, bipolar disorder, etc can be determined as well. In this case, however, scanning the patients head is necessary. By scanning the various hormones, chemicals as well the electrical currents that make up the inner working of the brain, the medical ninja can detect any inbalance and to what it might be due. He cannot read minds but he can understand if there is a disease or a Genjutsu present.

Additionally, all medical ninjas can use this skill to sense the patients chakra flow. Its by sensing the chakra flow that most of the times injuries and disease are noticed and diagnosed. Ninjas have their physical being greatly intertwined with their chakra, making so that an injury in one will result in changes to the other.

Finally, after gaining mastery over medical jutsu, a medical ninja becomes even able to examine dead bodies, determining cause and time of death.


Let me just explain how Shindan works a bit better, for everyone.

The idea behind it is that you will send your chakra through another body (your hands are the main focus here and its through its tenketsu that you'll release the chakra) and then will it to return to you with the information you need. That means that it doesn't matter whether you will touch the person or not or the location of your initial scan at all; the chakra will find the root of the problem and the manifestation of it. This is the information you require.

You can use chakra transmiting mediums, such as water, to improve you diagnosis and its effectiveness. The easier it is for your chakra to enter the body of the patient and return, the more information you'll be able to attain.

Now, to achieve this you need advanced chakra control and practice. Too much chakra and you risk harming the patient. Too little and you might not get enough information out of it.

What skills, KGs and abilities might help the medical ninja in this procedure?

Any advanced sensory enhacement helps the ninja adquire information in a more detailed manner, faster and without needing so much time. The main examples are:

-Sharingan: the ability to see your chakra flow and is characteristics as well as the ability to gain advanced visual perception in general helps to better identify the issues with the patient.

-Byakugan: perhaps the most useful of all the abilities that can help a medical ninja, the Byakugan allows you to see inside the body, piercing through the flesh and looking at the core issue in detail. Additionally, because you can see the chakra circulatory system completely and in detail, you can gauge the extent of the damage and if it somehow has anything to do with his chakra flow.

-Chakra Sensing: As said above, most injuries and diseases affect the chakra flow. By being able to sense disturbances in the chakra flow of your patients you are able to better understand their nature and extents.

-Enhanced Hearing: This can help you better evaluate biological functions such as breathing, heart function, intestinal function, blood circulation, blood pressure, etc.

-Emotion Sensing: While we talk about injuries of the flesh, the medical ninja also needs to treat injuries of the mind, often associated with Genjutsu. To better do this, sensing the emotions of your targets might help greatly.​

Medusa stops and asks the student
I want you to first, focus chakra into your core. Then channel it gently to your hands. Tell me how you feel. Focus the chakra around the entirety of your right hand and increase the chakra output while balancing it to be less aggressive and calm.

Next, I just injured a poor lab rat. Diagnose the rats injury(form your injury). What you need to do is just run your chakra coated hand across the body of the patient by making the chakra make contact, you'll be able to receive information of the patients anatomy and while you know a perfect one, once there is any anomally, you'll know.

 

[Jᴀʏ]

Killua would generate chakra in his core, mixing his spiritual and physical energies and releasing outwards a dark bluish chakra to his palm. He would balance the chakra, releasing it outwards at a constant rate but not too aggressive as his instructor had told him. I feel in control, Killua said hovering over the injured rat's body. He would use the chakra he released in order to assess the injuries. The injuries were simply superficial cuts, from Killua's knowledge of a healthy rat's anatomy this rat was missing flesh. The rat has suffered superficial flesh wounds. Killua said quite matter of factly.

 

[Klad]

I've been notified that Jay dropped Priest and I've been asked to continue this.

Teikouryoku (Power of Resistance)​

Before one can treat patients, one needs to protect himself. In real life, medical staff use gloves, masks, etc. But for a Medicla Ninja in a battlefield, thats not pratical. A Medical Ninja must always be aware of becoming a victim of whatever their patient is suffering from so he needs resistance to disease. With this skill you, as a Medical Ninja, increase your natural resistance to most natural diseases and toxins as well as most manmade diseases and poisons, allowing you to threat an infected or poisoned patient with a higher safety. It has no effect on diseases or poisons already affecting you though. This skill, as all others, improves as you grow in power and affords greater resistance to a wider range of diseases and poisons and can become something that you don't even need to focus to achieve.

However, there are limits. This skill will essentially provide a boost to your natural resistance to disease, poison, toxins, acids, alkaline substances, etc but will only basically provide a "shield" of sorts around you. This shield can be overcome, like all others, by overpowering it. This essentially means that you cannot use this to defend from enemy offensive techniques in the misdt of battle.

If you decide to and gain Poison Mastery, allowing you to make your own Custom Poison and mastery that branch of medical arts, this skill will allow you to become immune to regular none custom poisons and to your own poison.

How is it performed?

Now, to do this, you need to focus on your chakra at its core. This, when you look at the chakra circulatory system, is the central spiral network of chakra paths thats surrounds your chakra source, normally located in your abdomen. When you focus on it, you need to visualize a growing yellow and warm aura, spreading from your core, outwards towards your skin. Its this focus and this will that will make your chakra passively aggressive towards pathogens and most natural toxins and infectious diseases. This chakra is invisible to the naked eye and doesn't go beyond the users skin. However, doujutsu might see the aura growing and expanding from the medical ninjas core.

Its this a technique?

Teikouryoku is not a technique, has no chakra cost or is otherwise performed in any way remotely similar to a Jutsu. It is a passive skill, much like diagnosis, taught in the medschool, that gets stronger with time; the more you work with it, the better it will protect you against contagious diseases and poisons.

Are there different stages to its effectiveness?

Yes.

Medical Student: can maintain this skill active for a few minutes, enough to treat a single patient but needs effort and to will it to happen. Its impossible to keep active at all times.

Medical Ninja: the skill can be active for as long as he wishes and he doesn't need to dedicate any kind of mental command or focus for it to work.

Poison Master: Not only is the skill the same as the one for regular medical ninjas as it can protect the user from his own Custom Poisons and similar techniques (for example, toxic/poisonous/venomous elements) at all times.

Training:

Attempt to increase your resistance.

Questions?

 

[Jᴀʏ]

Alright so all I have to do is raise my resistance right? the young boy would think about the task for a moment, the resistance was more of a passive skill than an actual technique, and would allow him to become immune or resistant to toxins or poisons. The level of this resistance would naturally increase as the shinobi rose up the ranks. It seemed simple enough, but it was time to execute the task. Killua would begin to try and focus his your chakra at its core. Channeling the chakra to his central spiral network of chakra paths thats surrounds his chakra source, otherwise known as his abdomen. He would visualize a growing yellow and warm aura, spreading from his core, outwards towards his skin. The aura would act as a shield of sorts preventing things that might otherwise harm him (not offensive techs) and give him limited immunity. No questions.. Killua said as he kept attempting.

 

[Klad]

Alright, that was quite good.

Kiyomaru (Cleanse)​

As you might imagine, it is not always possible for a medical nin to practice basic hand washing and especially using an antiseptic to disinfect his/her hands. This technique has the effect of instantly removing bacteria, dirt, blood, and other contaminants from the users hands, lower arms, and face. It also insures that any breath that comes from the users body will be free of any bacteria or infectious disease. This technique can also be used to clean the wounds of others in order to prevent infection from bacteria.
Of course in the event that the medical nin is in need to use this technique to prevent infection of an injury that has been inflicted upon him-/herself, it is used as if the shinobi were using it on somebody else.
Now to the actual how to; as I implied above, our complete skin, and most of the mucous membranes are constantly covered with bacteria.. and other microbes. The only thing stopping those microorganisms from causing a disease is the fine balance of them and our physiological protective flora. The best way to describe this better is to give an example: our intestines are covered with millions of microorganisms, and when you get sick (like a cold or something) and you have to take antibiotics for whatever caused the cold, you actually disturb the physiological protective flora of your intestines, and therefore pathological bacteria prevail, and with their tocsins they start damaging the epithelial cells of your intestines thus causing diarrhea [this is for real btw. and I'm sorry for straying away that much lol].
You, with your chakra, can very easily disturb such a tiny energetic system. In order to make your chakra so aggressive you simply visualize how it starts being more agile, warmer and idk.. whatever you think of when you think "destroy >.<". Then you start sending it out from your palms, and while doing so, you simply run your hands over whatever you want to disinfect, be it your arms, face, or the patients wound (requires a different jutsu, since you have got to be careful not to disturb the actual patient’s chakra system). Once the bacteria’s energy system is disturbed, it simply dies because it's membrane starts failing and can no longer keep water inside, and so it dries out.

The method for cleaning yourself:

(Iryō Ninjutsu: Kirei Tomo) Medical Technique: I clean all of me
Type: Supplementary
Rank: C-Rank
Range: Short
Chakra Cost: 15
Damage Points: N/A
Description: The medical shinobi fills his palms with small amounts of extremely aggressive chakra and runs them over the areas of his body he wants to clean of any microorganisms, harmful substances, etc. The chakra will eliminate any inert harmful substance or microorganism present on that area. Normally this technique is done on the hands and lower arms just before having contact with a patient but can be applied to the whole body in specific situations (before performing surgery, if the enemy is highly contagious, etc). After being done, the chakra automatically turns back to his regular, non-harmful and calm one.

For cleaning someone else:

(Iryō Ninjutsu: Kirei Itto) Medical Technique: I clean all of him
Type: Supplementary
Rank: B-Rank
Range: Short
Chakra Cost: 20
Damage Points: N/A
Description: The medical shinobi fills his palms with moderate amounts of semi-aggressive chakra and runs them over any areas of the patient’s body he wants to clean of any microorganisms, controlling the chakra flow constantly so it doesn't becomes too lethal. The area affected is 4 times the area of the users hands. After being done, his chakra automatically turns back to his regular, non-harmful and calm one.

FAQ

Imagine I have access to pathological microorganism... let's say, hypothetically, fungus. How does the rank of these techniques interact with them? Is Med Nin stronger, double stronger, equal? And how would this technique interact in other types of battle applications? What about...lets say I have a mud jutsu, or a dirt jutsu, can I use this technique to coat my hand and body and neutralize it? Is this the same as basic ninjutsu in terms of power? For example, if this was raw ninjutsu, and, thus, weaker to elemental techniques, I'd be able to use it to neutralize a D rank lightning, allowing me to touch electricity, even if momentarily. If it's the same as strong raw ninjutsu, like the hyuuga rotation, then it would be neutral to elemental ninjutsu, so I'd be able to walk through D rank fireballs and the such, like a sort of body armour, as I have my body coated in chakra.

They are equals. Lets use Medical Ninjutsu: Strong Beam as the example.

(Iryo Ninjutsu: Tsuyoi Kōsen) Medical Ninjutsu: Strong Beam
Type: Offensive
Rank: A-Rank
Range: Short-Long
Chakra: 30
Damage: 60
Description: A high level medical technique in which the user gathers medical chakra, akin to the Shosen Jutsu technique, into his index and middle fingers, forming a dense chakra focus point. This chakra quickly changes from a light, translucent green to a heavy, bright red color as the user points his fingers outwards, unleashing a powerful chakra beam. The chakra beam, however, has different properties from normal chakra and, unlike the technique which serves as its basis, has no healing effect, quite the contrary. If it hits an enemy living organism, its aggressive nature injures the targeted tissues, creating an effect similar to a severe burn. The cells burst open as if having been hit by a high temperature, reducing themselves to a mushy pulp as the beam travels through them. If undefended, the beam can easily pierce through an enemy in a fast manner. The travelling speed of the beam is akin to that of a similar ranked lightning technique. The down side of the technique is that, when it collides with an elemental technique, it acts as a simple, concentrate chakra beam, capable of overcoming B-Rank defenses and only being negated by A-Rank ones.

That also accounts for all medical techniques, they are equal in terms of power and, just general everything. However, these techniques, their design is to clean all of him and you. They are mainly just used to kill microorganism/bacteria. They don't really have many battle applications. Sure, one can be inventive and try to find them but its likely that you can do the same in a better way with other techniques.

Can these be used to desinfect instruments and weapons from poisons and toxins?

Yes and no. Simple pathogens and microorganisms, etc. Poisons, no.

[Jᴀʏ]

Killua would listen to his instructor intently, it seemed cleansing oneself and one's target is a determinant to being a medical shinobi. Without disinfecting, the med ninja leaves his patients and himself vulnerable to a number of infections and toxins. Killua would keep this in mind as he turned to one of his class-mates. Killua would begin by channeling chakra in his palm, creating aggressive chakra that would vibrate rapidly. He would then hover his palm over his arms, he would alternate left to right and disinfect his entire arm up to and behind the elbow.

After cleaning himself Killua would turn to his partner, unlike with himself Killua would need to disinfect the problem area. When on the field, Killua wouldn't always have access to sterile or he just might not have the time. With this technique Killua was being as efficient as he could possibly be. He would channel chakra to his palm once again, vibrate the aggressive chakra and hover it over his partner's "wound" (abdomen) he would use the chakra to remove all the harmful pathogens and microorganisms. After completing the task, Killua would go back to his seat and await further instruction.

Interestingly enough, it seemed as though one could alter the aggressiveness of the chakra making it so potent that the chakra actually burn away tissue. A more aggressive, and battle oriented application of the cleansing process. "Hmm.."

Tekishutsu (Extraction)​

One of the most common things to happen to a ninja is to get a foreign object lodged somewhere in his or her body. Normally, this poses an issue as these objects tend to be weapons which are normally designed to inflict even more damage when forcefully removed from your flesh. Medical ninjas, however, can use this skill to, in tandem with other skills you'll learn like blood coagulation for example, remove an object lodged in a body without further damaging the tissue around it. So, when a patient's body has a foreign object in it, such as the point of a shuriken, a senbon needle, or an arrow, it is important to remove the object without further harming the patient. Using this technique the Medical Ninja places their hands on either side of the injured area and uses chakra to very carefully manipulate the surrounding tissues in order to remove the object without causing any further damage. Depending on the severity of the wound and nature of the object, it can take anywhere from a few seconds to a few minutes to remove it.

---

Training:

Remove various foreign objects from your partner (wood splinters, kunais, senbons, etc)

 

[Jᴀʏ]

It seemed his teacher now wanted him to extract foreign objects from his classmates, it seemed as though this was another universal skill that all Medical Shinobi should be adept at. Killua would not fall back, he would keep pushing forward to master the art of Medjutsu. It seemed as though the most important thing when extracting something that has lodged itself into the bodies of ninja is caution. Be careful, because you could easily cause severe internal damage like rupturing an organ when performing a task such as this. Killua had already cleaned himself and his subject, using the mildly aggressive chakra his instructor had mentioned earlier on in the lesson. Killua after killing the micro-organsims would take a look at the injury, giving more diagnosis. It seemed it was a steel shard lodged into the back of this poor ninja, luckly it hadn't pierced too deep and was far from any organs. Killua would grab a scalpel and a clamp. He would use the scalpel to help space the shard from the skin, as he pulled the shard out with a clamp. After pulling the shard out, he would sterlize the wound and bandage it up. There we go...

Kuchiyose No Jutsu (Summoning Medical Tools)​

A medical ninja, regardless of his skill, will always face situations in which he'll need medical tools to treat patients. Be it to create antidotes or medicine, but to also stitch or bandage wounds, you'll always need to make sure you can access medical tools and supplies to treat patients.

*Hands out a scroll to each of you*

This technique allows a Medical Ninja to summon some of the tools of their trade. It is not practical to carry around syringes, scalpels and other tools but a scroll that can be used to summon these and other similar objects is both practical and convenient.

So as for any good summoning jutsu, you need your blood and a few kanji which you can all find in your scroll. You are expected to carry it with you at all times. It includes:

(Kuchiyose No Jutsu: Eisei Yougu) Summoning technique: Medical tools
Type: Supplementary
Rank: B-Rank
Range: N/A
Chakra cost: 20
Damage: N/A
Description: The medical Ninja will bite his thumb and do the summoning handseals before pressing his palm on the scroll. He will summon any of the medical tools he needs that are listed on the scroll, all or just one, depending on his own needs.
Note: This can only be used by Medical Shinobi.

メス - scalpel, sterilized
ナイフ - knife
アルコール - a bottle of 96% ethanol for disinfection
水 - a bottle of sterilized water
スポイト - syringe, sterile, for one time use only
アドレナリン - adrenaline, to be injected intravasulary, induces faster heartbeat
包帯 - bandage, sterile, 8 meters in length
血液 - a set of everything you need to draw someones blood (Sterile syringe, vacuum system and a test tube.)
温度計 - mercury thermometer, for axillary or rectal use
ベッド - a mobile bed to carry patients
バグ - bug spray, effective against all bugs, lasts for 2 turns (used in cases when your patient is having a reaction to multiple bug stings, and there are still some bugs around it, so you spray-kill them. Kills bugs up to A rank if they've been created/summoned from a jutsu like the Aburame techniques)
テント - a small tent, just enough for two people to lie in
光 - a flashlight
ガスマスク - gas mask with a bottle of oxygen that lasts 5 turns (Not 100% effective against all types of poison/gas. The purpose is to protect the user from breathing in toxic substances, keeping the lungs safe. However, if the poison gets absorbed through the pores of the skin it will still affect you).
流体 - a set to start an intravenous fluid addition line, helpful with dehydration amongst many other conditions
モルタル - mortar and pestle, chemically clean
スプーン - spoon, sterile
パテ - putty knife, metal, sterile
研究所 - a small tent. Into the walls of that house, parts of Nexus' eyes DNA have been inserted, so now it mixes Time And Relative Dimensions In Space , creating an effect of being larger on the inside then it is on the outside. Inside is an advanced ninja laboratory with everything needed to create antidotes and medicines.

Homework:

Pick 3 medical tools and explain how they can be helpful to you as a medical ninja.

 

[Jᴀʏ]

Adrenaline: Useful in many cases to keep the patients heart pumping, and to keep them alive. Using adrenaline while the patient is slipping off may help to keep them alive.
Sterile Scalpel: Useful tool used in order to cut into the patient, usually in order to extract a foreign object lodged within the patient or to implant something. In any case it's a universal tool used by all medical shinobi and it is very useful for battle as well.
Bandages: This is useful for closing wounds when you don't have access to Mystique Palm, the user can use this to help the healing process and to prevent the wound from getting infected.

Killua would say all this fluently and confidently.

 

[Klad]

Keksuki Gyouko (Blood Coagulation)​

This is a fairly simple healing skill that takes a single turn and costs no chakra. The user uses his chakra on a wound to make the blood there coagulate and stop bleeding. This is primarily used as a preliminary treatment option as it does not close wounds. The bleeding from superficial wounds can easily be stopped while we're at it, but deep wounds and "blood leakages" can require several minutes to stop, or can't be stopped at all; meaning simply you can't stop every bleeding, sometimes it takes surgery or so larger scale procedures. All in all, this is ideal for superficial wounds - doesn't requires much work, but stops the bleeding.

Spoiler

Although most of you covered the basis, I cannot correct each of your works individually pointing out what was missing or not so I'll simply make a small concise explanation of what I want you guys to know.

The Coagulation process is one of the most basic but yet complicated processes of the human metabolism (and all animals with blood). In simple terms, its the process through which blood becomes thicker and ultimately solid (cloth) if necessary; its the process through which blood thickness is altered. Taking this basic idea, Blood Coagulation is often dispicted as a stagnant occurrence, triggered only when a trauma occurs and hemostasis is needed.. However, its beyond that idea and is actually an active process constantly changing and balancing the blood's fluidity.

Its a simple idea, although the process itself is complicated. The blood, as a fluid, tends to escape the pathways through which it circulates. These pathways are the blood vessels (arteries and veins). Blood vessels have, inherently a given permeability to enable exchanges between the blood and the cells on the outside of the vessel. The coagulation process serves as a basis for these exchanges to work and is constantly adjusting the blood fluidity in order to keep it flowing in a correct way, containing it in the vessels but maintaining circulation. If the blood is too thin and fluid it will escape the vessels and a passive hemorrhage occurs, disabling the normal exchanging process. If the blood is too thick, it will form cloths, clogging the blood vessel and preventing circulation (trombosis).

This is the process that keeps working 24/7 on adjusting the blood in order for the human body to work and is an automated passive process of our metabolism. Many factors revolve around them and I don't expect you guys to know them all obviously. Vitamin K, Platelets, Fibrogen, Colagen, Water, Ionic Concentrations, Genetic Intrinsic Factors (also named often the coagulation factors), etc all play a part in keeping the passive balance in order. However, this process serves another purpose, which is the main one for our application here in Med School. If blood vessels are ruptured, the blood spills outside of them and a traumatic hemorrhage occurs. Because blood is one of the core participants in the metabolism, the organism can't afford to lose too much of it, so it has to stop the bleeding. This is done through the hemostasis process, a process through which blood is used to produce a cloth of platelets and fribin in the rupture, stopping the bleeding and enabling the repairs to start.

Coagulation works through 2 main factors: The Cell Factor (platelets) and the Protein Factor (Coagulation factor). Basically and resuming it way down since I only want you guys to hav an idea of it, not all the medical details, when a tissue is ruptured and cells are damaged, a special batch of proteins are scattered throughout the wound and surrounding area (they are released as a byproduct of the traumatic destruction of the cells and celular tissue). When the blood comes in contact with these proteins, the platelets and a special protein in the plasm (the "water" base of the blood where all the nutrients and minerals and etc are transported) called fribrogen changes and immediately the primary hemostasis occurs, as a "tampon" of aggregated platelets forms at the rupture, stopping the bleeding. At the same time,the secondary hemostasis ocurrs, through which a complicated chemical and physical reaction ocurrs in the proteins in the plasma, triggering a cascade of reactions that has the byproduct of producing fibrin strands that strengthened the platelet "tampon" and form the definitive cloth. These proteins in the plasma and the cascade reaction of them is the process through which blood becomes thinner or thicker, by the presence of more or less fibrin and its thicker or thinner structure. Fibrin is a thick and gel like protein that combines with water to give plasma its main body (and through more or less "gel", more or less thicker it becomes).

Okay, so, with my explanation and while writing your homework, you all learned (hopefully) what's the basis needed for blood to coagulate. This technique and the procedure around it doesn't makes it do so, and there is nothing you can do to make successful blood coagulation occur, because it is simply too complicated and has too many factors involved. What you can do, however, is help the body while it's trying to do it on its own. This implies that the patients blood has to be able to coagulate on its own already, meaning that all coagulation factors must be present and functioning in his body, he has to have blood, etc. This means that you simply make your patients blood coagulate faster than normal by aiding it with your chakra.

You do so by laying your hand on the wound and infusing it with your chakra, molding, willing your chakra to be of a certain nature that will help the body in the coagulation process; and you do so by simply imagining the chakra how it goes to the blood vessel and starts sticking fibrin and blood platelets together over the damaged area. Pretty simple and doesn't count as a move or requires a technique.

Are there any questions?

Homework:

Explain how blood coagulation works in your own words and how it relates to narutoverse, chakra and a medical ninja's role.

 

[Jᴀʏ]

Blood Coagulation naturally occurs when the user has undergone a physical trauma to a large degree, since blood is an important factor of homeostasis, the user cannot afford to lose much of this. And so Med Ninja have devised a method to trigger this natural process through their chakra, the Blood Coagulation refers to the thickening of blood. When the users blood is thickened to a gel-like or semi-solid state it prevents the blood from pouring out of the users system. Effectively eliminating the chance of dying from blood loss. The user triggers this through their chakra, manipulating the Coagulation Factors within the patients body that is activated when the target has undergone a significant physical trauma. The user will activate these various vitamins and proteins, triggering the Coagulation Process. This requires no chakra and is only effective on certain wounds like superficial wounds, other wounds might require surgery. Yup that's how it works.

Chishio Tensou no Jutsu (Blood Transfusion Skill)​

Loss of blood is a serious condition, and a not very uncommon one in the shinobi battlefield. When a person reaches such a dangerous state, a Medical Ninja can ease their symptoms by using this jutsu. First, the medical nin places a surgically precise cut on the patient and then another cut on the donor. The donor and the recipient must have their respective cuts within six inches of each other; this is typically accomplished by cutting their opposing arms and having them lay beside each other. The Medical Ninja then forms a sphere of chakra between the two cuts drawing out blood from both patients and altering it so that the blood type of the donor matches that of the recipient. It is important to remember that taking more than 1 pint of blood from a donor is extremely dangerous, even with the loss of only 1 pint of blood the donor may suffer from dizziness and fatigue.

The Technique:

(Iryō Ninjutsu: Chishio Tensou no Jutsu) Medical Technique: Blood transfusion Technique
Type: Supplementary
Rank: A-Rank
Range: Short
Chakra Cost: 30 (per turn)
Damage Points: N/A
Description: Once the Medical Ninja has a donor (a willing one or not), he or she makes two small cuts, one on the patient, and one on the donor, placing them side by side so it is easy to put those cuts about 30 cms apart. Then the Nin forms a chakra orb which then transfuses the blood from the donor to the patient. The technique requires high levels of chakra control and can even change the blood type of the donor to match that of the patient.
Note: It transfers 400ml of blood per turn

Blood Loss is a serious condition, At first the blood loss will only present itself a slight dizziness, and as the patient begins to lose more blood the user will get pale, and dizziness will become fatigue. As the user begins to lose more blood oxygen is stopped from being pumped to organs, and the patient suffers from organ failure. The patient can even die if not treated, that's why Blood Transfusions are so important. Thats why ya boy a universal donor.
