GENERAL HISTOLOGY

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: -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-3: -Vasopressin (also called antidiuretic hormone) plays a role in regulating the circadian rhythm-the periods of sleepiness and wakefulness in a 24-hour cycle. Vasopressin also helps maintain the body’s internal temperature, its blood volume, and the proper flow of urine from the kidneys.

Detailed explanation-4: -In general, vasopressin decreases water excretion by the kidneys by increasing water reabsorption in the collecting ducts, hence its other name of antidiuretic hormone. Vasopressin also has a potent constricting effect on arterioles throughout the body.

Detailed explanation-5: -However, with severe degrees of dehydration, thirst is essential to restore body water deficits. Vasopressin acts on the V2 subtype of vasopressin receptors in the collecting duct principal cells of the kidney to cause water retention, or antidiuresis.
