Vasopressin, also known as antidiuretic hormone (ADH), controls water reabsorption only in the distal and collecting tubules of the nephron. Vasopressin causes the insertion of aquaporin-2 channels in the apical membrane of the cells lining these tubules, allowing for water to be reabsorbed back into the body. This mechanism helps to maintain body fluid balance and prevent dehydration.
