WTF?:|:|:|:|
that is a panel from chapter 606 i got. It suggest Uzumaki came from Senju.
Fine here is another one:

The Senju and Uzumaki are distant relatives through bloodline. BTW this is a VIZ translation so there isn't anything wrong with it.
moving on...
if were were to take Kushina's statement in conjunction with Zetsu statement, then the most accurate meaning of the context you can pull from Kushina's statement and Zetsu's statement is this:
1)Bloodline: A set of ancestors or line of descent of a person.
2)distant relatives:Close family relation such as a parent or sibling
3)Lineage

irect descent from a particular ancestor; ancestry
definitions of words meanings and the best you can describe their relationship is:
Uzumaki direct relatives/descendants to the Senju through their bloodline which the Yang/Physical Energy they inherited from SO6P. Uzumaki are more like grand children to the Senju.
