Detailed explanation-1: -CAUSES. ADH, also known as vasopressin, normally is secreted in response to an increase in serum osmolality (serum sodium concentration) or to maintain normal blood pressure and intravascular volume (see Chapter 177, Vasopressin). ADH actions are achieved by the promotion of free water resorption by the kidneys.
Detailed explanation-2: -A decrease in blood volume or low blood pressure, which occurs during dehydration or a haemorrhage, is detected by sensors (baroreceptors) in the heart and large blood vessels. These stimulate anti-diuretic hormone release.
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: -When someone drinks lots of water, requirement of absorption of water decreases, so ADH release is suppressed. Q. Drinking lots of water is important for the health of kidneys. Why?
