How does adh affect aquaporins
WebSep 24, 2024 · How does ADH regulate the amount of water excreted? The principal action of ADH is to regulate the amount of water excreted by the kidneys. Water moves out of the kidney tubules through the aquaporins, reducing urine volume. The water is reabsorbed into the capillaries lowering blood osmolarity back toward normal. 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.
