Detailed explanation-1: -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-2: -ADH primarily affects the ability of the kidney to reabsorb water; when present, ADH induces expression of water transport proteins in the late distal tubule and collecting duct to increase water reabsorption. Several disease states arise when the body loses control of ADH secretion or responds to its presence.
Detailed explanation-3: -Aldosterone causes an increase in salt and water reabsorption into the bloodstream from the kidney thereby increasing the blood volume, restoring salt levels and blood pressure.
Detailed explanation-4: -Antidiuretic hormone (ADH)-produced by the posterior pituitary gland-increases the amount of water reabsorbed in the distal convoluted tubule and collecting duct. Osmoreceptors in the hypothalamus signal the posterior pituitary gland to increase ADH secretion when plasma osmolarity becomes too high.
Detailed explanation-5: -Its most important role is to conserve the fluid volume of your body by reducing the amount of water passed out in the urine. It does this by allowing water in the urine to be taken back into the body in a specific area of the kidney.
