PATHOLOGY

Detailed explanation-1: -Antidiuretic hormone (ADH) helps regulate the amount of water in your body. It works to control the amount of water your kidneys reabsorb as they filter out waste from your blood. This hormone is also called arginine vasopressin (AVP).

Detailed explanation-2: -(AN-tee-DY-yoo-REH-tik HOR-mone) A hormone that helps blood vessels constrict and helps the kidneys control the amount of water and salt in the body. This helps control blood pressure and the amount of urine that is made.

Detailed explanation-3: -ADH travels in the bloodstream to the kidneys. Once at the kidneys, ADH changes the kidneys to become more permeable to water by temporarily inserting water channels, aquaporins, into the kidney tubules. Water moves out of the kidney tubules through the aquaporins, reducing urine volume.

Detailed explanation-4: -ADH causes the walls of the distal convoluted tubule and collecting duct to become permeable to water-this drastically increases the amount of water that is reabsorbed during tubular reabsorption.
