Question

The action of angiotensin II is to do which of the following?
A) Maintain sodium in the blood
B) Balance water in the plasma
C) Maintain blood pressure
D) Both maintain sodium in the blood and balance water in the plasma
E) All of these are correct.

Accepted Answer

Angiotensin II plays a crucial role in regulating blood pressure by constricting blood vessels, which directly affects blood pressure maintenance. It also promotes sodium retention in the kidneys, which helps maintain sodium levels in the blood, and indirectly influences water retention, thereby balancing water in the plasma. Thus, all of the listed actions are correct.
