Answer 1

Answer:

A.when there is more sodium in the blood ,the aldosterone level is decreased and the re absorption of sodium is also decreased

Explanation:

Aldosterone is a hormone that is excreted by the adernal cortex of the kidney

and it acts on the collecting tubules and distal tubules to conserve the sodium and retain the water and excrete potassium ions.

It Increases the blood pressure .

If there is excess of sodium retention ,the body signals to decrease the secretion of the aldosterone and maintain the body osmolarity .
