blood helps maintain homeostasis by all of these mechanisms EXCEPT:

a. eliminates waste products
b. protects about foreign substances
c. transports nutrients and gases
d. regulates pH
e. clot formation

I don't totally understand this question. I know that if O2 levels decrease the EPO will be released- hence homeostasis of o2 levels, but I'm blank on the others.

The question is basically asking which one of the 5 are not involved with the blood homeostasis properties.
I have since figured it out.
the answer is A as it is not homeostasis/negative feedback. all the others can be reverse/taken to completion.
