In which part of nephron is water reabsorbed
WebThe hormone antidiuretic hormone or ADH controls the extent to which water is reabsorbed. If blood is concentrated, more ADH is released which makes the walls of the collecting duct more permeable to water, allowing more to be reabsorbed. If blood is more dilute, less ADH is released and so less water is reabsorbed. WebEach of these carries out a specific function. The proximal nephron absorbs about two-thirds of filtered sodium, without dissociating salt and water absorption. The thick …
