Question

Which of the following is not a function of angiotensin II?

• A. Vasoconstriction
• B. Increases the glomerular blood pressure
• C. Decreases the GFR
• D. Increases the blood pressure

Answer 1

Answer: (C)

Angiotensin, specifically angiotensin II, binds to many receptors in the body to affect several systems. It can increase blood pressure by constricting the blood vessels.
In the adrenal glands, angiotensin stimulates aldosterone production. This hormone causes the body to retain sodium, causing increased water re-absorption to increase the volume of blood. It increases GFR.
