Correct Answer: B
Explanation:
Antidiuretic hormone (ADH) also known as arginine, vasopressin (AVP), or argipressin is a neurohypophysial hormone found in most mammals. Its two primary functions are to retain water in the body and to constrict blood vessels. ADH regulates the body's retention of water by acting to increase water reabsorption in the collecting ducts of the nephron, which is the functional component of the kidney. ADH is a peptide hormone that increases water permeability of the kidney's collecting duct and distal convoluted tubule by inducing translocation of aquaporin-CD water channels in the kidney nephron collecting duct plasma membrane. It also increases peripheral vascular resistance, which in turn increases arterial blood pressure. It plays a key role in homeostasis, by the regulation of water, glucose, and salts in the blood.
