Vasopressin/antidiuretic hormone

Question

Quizplus · Accepted Answer

Vasopressin, also known as antidiuretic hormone (ADH), is a peptide hormone released from the posterior pituitary gland. Its primary function is to promote the retention of water in the body by triggering the insertion of aquaporins into the luminal membranes of collecting ducts, which allows water reabsorption. This results in a smaller volume of urine production. Therefore, choice B is the best answer as it accurately describes vasopressin's action.
