The hormone aldosterone regulates water reabsorption in the distal convoluted tubules. It works by increasing the reabsorption of sodium ions, which in turn triggers the reabsorption of water from the tubules back into the bloodstream.
Reabsorption is the process by which molecules move from the proximal convoluted tubule into the blood.
The proximal convoluted tubule
The distal convoluted tubule or the collecting tube.
The maximum reabsorption of water occurs in the proximal convoluted tubule of the nephron in the kidneys. Approximately 65-70% of the filtered water is reabsorbed here, along with a significant amount of solutes. Additional water reabsorption takes place in the loop of Henle, distal convoluted tubule, and collecting ducts, but the proximal convoluted tubule is where the majority occurs.
Selective reabsorption of glucose occurs in the proximal convoluted tubule of the nephron. Glucose is filtered out of the blood in the glomerulus, and then reabsorbed back into the blood through the walls of the proximal convoluted tubule.
proximal convoluted tubule
The largest volume of water reabsorption in the kidneys occurs in the proximal convoluted tubule. This is the first segment of the renal tubule where approximately 65-70% of the filtered water is reabsorbed back into the bloodstream.
The reabsorption of glucose primarily occurs in the proximal convoluted tubule of the nephron in the kidney. Glucose is filtered out of the blood in the glomerulus, and then most of it is reabsorbed back into the bloodstream in the proximal convoluted tubule to prevent its loss in the urine.

Aldosterone acts on the distal convoluted tubule and collecting duct in the kidney to increase sodium reabsorption and potassium secretion.
