Detailed explanation-1: -Aldosterone causes sodium to be absorbed and potassium to be excreted into the lumen by principal cells. In alpha intercalated cells, located in the late distal tubule and collecting duct, hydrogen ions and potassium ions are exchanged.
Detailed explanation-2: -Aldosterone is a hormone produced in the cortex of the adrenal glands, which are located above the kidneys. The hormone causes the reabsorption of water with the sodium to increase blood volume.
Detailed explanation-3: -Water Reabsorption in the Collecting Duct ADH is produced in the hypothalamus, and stored in the posterior pituitary gland until it is released. This hormone acts on kidney tubules to increase the number of aquaporin 2 channels (water channels) in the apical membrane of collecting duct tubular cells.
