ANATOMY

Detailed explanation-1: -Antidiuretic hormone (ADH) induces water retention by increasing the permeability of nephrons. Its influence on water permeability occurs primarily by regulating aquaporin 2 water channels in the distal tubules and collecting ducts of the kidney (Kwon et al., 2001).

Detailed explanation-2: -ADH enables the kidneys to retain water in the body. The hormone is produced in a region of the brain called the hypothalamus.

Detailed explanation-3: -Vasopressin (also called antidiuretic hormone) helps regulate the amount of water in the body by controlling how much water is excreted by the kidneys. Vasopressin decreases water excretion by the kidneys. As a result, more water is retained in the body, which dilutes the level of sodium in the body.

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.
