Answer 25

from Kidney | function: stimulates red blood cell production in bone manrrow

Question 26

Calcitriol

Answer 26

From Kidney | Function: Increases body calcium ( is the active form of vitamin D)

Question 27

Angiotensinogen

Answer 27

From: Liver Function: converted in blood to angiotensin II, which stimulates aldosterone secretion, promotes thirst, and causes vasoconstriction and secretion of vasopressin.

Question 28

Insulin- like growth factors (somatomedins)

Answer 28

From Liver | Function: promote cell division and growth of many tissues. (Also secreted by other tissues like muscle)

Question 29
