Which of the Following is a Function of Antidiuretic Hormone

Question

Which of the following is a function of antidiuretic hormone ADH)?
A) ADH alters the ion reabsorption by the loop of Henle.
B) ADH decreases the reabsorption of urea, creating a higher urea content in the urine.
C) ADH improves the reabsorption of glucose by the proximal convoluted tubule.
D) ADH triggers the insertion of water channels called aquaporins, thereby increasing the amount of water reabsorbed by the collecting duct.
E) ADH triggers the insertion of water channels called aquaporins, thereby reducing the amount of water reabsorbed by the collecting duct.

Accepted Answer

ADH triggers the insertion of water channels called aquaporins, thereby increasing the amount of water reabsorbed by the collecting duct. This helps to prevent excess water loss in urine and maintain the body's water balance.
