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 also causes the epithelial cells that line the renal collecting tubules to move water channel proteins, called aquaporins, from the interior of the cells to the apical surface, where these proteins are inserted into the cell membrane. The result is an increase in the water permeability of these cells and, thus, a large increase in water ...
