Question

Reabsorption of water in the kidney is under the control of

• A. ADH (Antidiuretic Hormone)
• B. ACTH(Adrenocorticotropic Hormone)
• C. LT(Luteinising Hormone)
• D. FAH( Fumarylacetoacetate Hydrolase)

Answer 1

The correct option is A ADH (Antidiuretic Hormone)

The reabsorption of water in the kidney is under the control of ADH. It trigger the release of aldosterone which increase the concentration of sodium ions in blood. The increased sodium concentration in the blood increases the blood osmotic potential which further increases the reabsorption of water into the collecting tubule.
