WebJan 5, 2024 · What happens to the urinary system when ADH levels increase? An increase in ADH results in the production of a small volume of concentrated urine. When ADH levels decrease, the distal convoluted tubules and collecting ducts become less permeable to water. As a result less water is reabsorbed, and a large volume of dilute urine is produced.

WebADH acts on the kidneys to enhance a number of processes that concentrate the urine (See: ECF Osmoregulation ). This includes increasing the water-permeability of the late distal tubule and collecting duct by promoting placement of aquaporins on … WebThis hormone triggers chemical reactions that ultimately insert aquaporin 2 water channels into the membrane of collecting duct cells. These channels allow water to be reabsorbed into the bloodstream, which makes the urine more concentrated. When fluid intake is adequate, less ADH is produced. WebJul 31, 2024 · ADH travels round the body in the blood until it reaches its target tissue which are the cells that line the collecting ductsin the nephronsin the kidney. ADH increases the permeability of the connecting duct walls to water, thus meaning more water is reabsorbed by osmosis from the urine in the collecting duct and back into the blood. in your blue eyes hayward
