Detailed explanation-1: -As a result, the reabsorption of water from the glomerular filtrate is increased. When someone drinks lots of water, requirement of absorption of water decreases, so ADH release is suppressed.
Detailed explanation-2: -Answer and Explanation: The true statement about the role of antidiuretic hormone (ADH) in regulating kidney function is C. ADH promotes the insertion of water channels into the collecting duct. The action of ADH is dependent on reabsorption of water into the system so that balance of water can be maintained.
Detailed explanation-3: -Anti-diuretic hormone acts to maintain blood pressure, blood volume and tissue water content by controlling the amount of water and hence the concentration of urine excreted by the kidney.
Detailed explanation-4: -ADH is released by the pituitary gland when the blood is too concentrated and it causes the kidney tubules to become more permeable . This allows more water to be reabsorbed back into the blood during selective reabsorption.
