Question

Discuss the mechanisms and consequences of ADH and aldosterone on the kidneys, in detail.

Answer 1

Answer:

Anti-diuretic hormone or ADH is a hormone which helps in reabsorption of water, maintaining blood volume, blood pressure and homeostasis in the body.

Aldosterone is the hormone which helps in the reabsorption of the electrolyte in the tubules of the kidney.

Aldosterone acts by opening the ion channels which allow the re-absorption of electrolytes like Na⁺ ions, Cl⁻ ions whereas  ADH acts by opening the aquaporin-2 channels in the collecting duct which allow the absorption of water molecules from the solution.

These hormone helps forms the concentrated urine as the electrolyte and water get re-absorbed.
