Detailed explanation-1: -Water levels in the body are controlled by antidiuretic hormone (ADH), which is produced in the hypothalamus and triggers the reabsorption of water by the kidneys.

Detailed explanation-2: -ADH increases water and urea permeability of the distal nephron, leading to excretion of a small volume of concentrated urine, thereby minimizing further loss of blood volume and decreasing the osmolarity of the plasma back toward normal.

Detailed explanation-3: -Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced. A high ADH level causes the body to produce less urine. A low level results in greater urine production.

Detailed explanation-4: -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-5: -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.
