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. WebADH makes collecting ducts more permeable to water by stimulating the activity of aquaporins in the membranes of collecting duct cells.. How does ADH affect water reabsorption? ADH is an anti-diuretic hormone secreted by the hypothalamus. The hypothalamus is located in the brain. It is an area that controls many bodily functions. photo hex picker

http://www.pathwaymedicine.org/ADH-Physiology 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 does this by causing an increase in the number of aquaporins (water-permeable channels) in the luminal membranes of the collecting duct cells. This occurs in the following way: Collecting duct cells contain vesicles, the membranes of …
