2) afferent arteriole

3) collecting duct

4) proximal convoluted tubule

Answer 1

ANSWER.

1) Aldosterone is a mineralocorticoid that stimulates the reabsorption of sodium.

3) Aldosterone exert it's effect on distal convoluted tubule.

    It helps to the reabsorption of sodium from the distal convoluted tubule to the
