Detailed explanation-1: -When the water potential is low (so the blood has a high solute concentration), these osmoreceptor cells lose water by osmosis and shrink, causing the release of a peptide hormone called ADH (vasopressin/anti-diruretic hormone). ADH passes to the posterior pituitary gland and is secreted into the capillaries.
Detailed explanation-2: -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-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: -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.
