PATHOLOGY

Detailed explanation-1: -When the body is low in water, the pituitary gland secretes vasopressin (also called antidiuretic hormone) into the bloodstream. Vasopressin stimulates the kidneys to conserve water and excrete less urine.

Detailed explanation-2: -Antidiuretic hormone (vasopressin) Affects water retention in kidneys and sodium balance.

Detailed explanation-3: -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-4: -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-5: -Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of “water channels” or aquaporins into the membranes of kidney tubules. These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.
