Two hormones are closely involved in the regulation of the fluid and electrolyte balance of the body. Name them and explain their effects on their common target organ.

Answer: Anti-diuretic hormone also known as vasopressin and Aldosterone

Explanation:

They both act on the kidneys to exert their effect.

Anti-diuretic hormone acts on the kidney to regulate Urine volume, thus causing the kidney to reabsorb water from the urine.

Aldosterone acts on the kidneys to increase sodium retention. Increased sodium retention leads to increased water retention.
