Question

Name the hormone which is responsible for reabsorption of water in nephrons

Answer 1

Antidiuretic hormone 
binds to receptors on cells in the collecting ducts of the kidney and promotes reabsorption of water back into the circulation. In the absence of antidiuretic hormone, the collecting ducts are virtually impermeable to water, and it flows out as urine

Answer 2

Nephrons are the functional units present in both the kidneys and are responsible for removal of nitrogenous waste and excess water from the body

Explanation:

Some times a part of the water filtered out in glomerulous is required in the body to maintain the electrolytic balance. The body therefore releases a hormone to induce re-absorption of water.

Anti-diuretic hormone promotes this re-absorption of water into the nephron.
