Webinsipidus, water reabsorption in the kidney is decreased dramatically and large volumes of dilute urine are excreted, up to 25 liters per day! Aldosterone is a hormone that regulates blood sodium levels. Aldosterone specifically increases sodium reabsorption in the distal convoluted tubule and collecting duct of the nephrons in the kidneys. WebSodium reabsorption in the late distal tubule and collecting duct is regulated by hormones, which stimulate or inhibit sodium reabsorption as necessary. Other ions : Calcium reabsorption throughout the nephron is largely similar to sodium reabsorption …

WebAs noted above, ADH plays a role in lowering osmolarity (reducing sodium concentration) by increasing water reabsorption in the kidneys, thus helping to dilute bodily fluids. To prevent osmolarity from decreasing below normal, the kidneys also have a regulated mechanism for reabsorbing sodium in the distal nephron.
