An action of renin is the:
|\ |\ |\ |\ |\




1) inactivation of autoregulation
|\ |\ |\




2) direct activation of angiotensin II
|\ |\ |\ |\ |\




3) direct release of ADH
|\ |\ |\ |\




4) activation of angiotensin I - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\



✔✔activation of angiotensin I |\ |\ |\




When renin is released, it cleaves an a-globulin
|\ |\ |\ |\ |\ |\ |\ |\



(angiotensinogen produced by liver hepatocytes) in the |\ |\ |\ |\ |\ |\ |\



plasma to form angiotensin I, which is physiologically
|\ |\ |\ |\ |\ |\ |\ |\



inactive.

,Which of the following is found in older adults?
|\ |\ |\ |\ |\ |\ |\ |\




1) A sharp decline in GFR and no change in renal blood
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



flow
2) A sharp decline in renal blood flow and in GFR
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\




3) A decrease in the number of nephrons
|\ |\ |\ |\ |\ |\ |\




4) An increase in GFR leading to increased urine output -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



CORRECT ANSWERS ✔✔A decrease in the number of
|\ |\ |\ |\ |\ |\ |\ |\



nephrons
