Detailed explanation-1: -ADH facilitates water reabsorption from latter parts of the tubule (Distal convoluted tubule and Collecting duct), thereby preventing diuresis.

Detailed explanation-2: -ADH Controls Distal Nephron Permeability. ADH increases the water permeability of the late distal tubule (or connecting duct) and all parts of the collecting duct. It also increases the urea permeability of the inner medullary collecting duct.

Detailed explanation-3: -Antidiuretic hormone binds to receptors on cells in the collecting ducts of the kidney and promotes reabsorption of water back into the circulation. In the absense of antidiuretic hormone, the collecting ducts are virtually impermiable to water, and it flows out as urine.

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.

Detailed explanation-5: -ADH is a hormone that increases permeability to water in the collecting ducts and therefore increases water reabsorption from the urine. This decreases the volume of water in the urine.
