ANATOMY

Detailed explanation-1: -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. Antidiuretic hormone is made by a part of the brain called the hypothalamus and is secreted into the blood by the pituitary gland.

Detailed explanation-2: -Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced.

Detailed explanation-3: -The ADH is activated by the posterior portion of the pituitary gland. The anti-diuretic hormone is secreted by the neurohypophysis of the pituitary gland. Since it stimulates the constriction of blood vessels and results in an increase in blood pressure, therefore it is called vasopressin.

Detailed explanation-4: -Higher concentrations of anti-diuretic hormone cause blood vessels to constrict (become narrower) and this increases blood pressure. A deficiency of body fluid (dehydration) can only be finally restored by increasing water intake.

Detailed explanation-5: -The posterior lobe of the pituitary gland stores and releases (secretes) only two hormones: Antidiuretic hormone (ADH, or vasopressin): ADH helps regulate the water balance in your body by controlling the amount of water your kidneys reabsorb while they’re filtering wastes out of your blood.
