Detailed explanation-1: -Explanation: ADH acts upon the collecting ducts and distal convoluted tubules of nephrons to increase water reabsorption. It causes an increase in the number of aquaporins in order to allow for this.
Detailed explanation-2: -The proximal convoluted tubule is involved in the reabsorption of water, sodium ions, chloride ions, and sugar from the glomerular filtrate. It functions even in presence of the hormone ADH (Anti-diuretic hormone).
Detailed explanation-3: -Physiologic Effects of Antidiuretic Hormone 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 absense of antidiuretic hormone, the collecting ducts are virtually impermiable to water, and it flows out as urine.
