Question

which are characteristics of aldosterone to increase blood pressure? select all that apply.
a it increases sodium reabsorption.
b it increases water reabsorption.
c it decreases sodium reabsorption.
d it decreases water reabsorption.

Explanation:

Aldosterone is a hormone that regulates blood pressure. It acts on the kidneys to increase sodium reabsorption (A is correct, C is incorrect). Increased sodium reabsorption leads to increased water reabsorption (due to osmosis, so B is correct, D is incorrect) as water follows sodium. This increases blood volume and thus blood pressure.

Answer:

A. It increases sodium reabsorption, B. It increases water reabsorption
