increases reabsorption of water

Detailed explanation-1: -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-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.
Detailed explanation-3: -Direct control of water excretion in the kidneys is exercised by vasopressin, or anti-diuretic hormone (ADH), a peptide hormone secreted by the hypothalamus. ADH causes the insertion of water channels into the membranes of cells lining the collecting ducts, allowing water reabsorption to occur.
Detailed explanation-4: -ADH decreases the volume of urine by increasing the reabsorption of water in the kidneys. ADH causes contraction of vascular smooth muscles, constriction of arterioles, and peripheral vasoconstriction.
Detailed explanation-5: -If your body produces too much ADH and water is retained, your blood volume increases and leads to symptoms like: Feeling nauseous. Headaches. Disorientation‌
