Proximal Convoluted Tubule
Most water reabsorption in the body occurs in the proximal convoluted tubule of the kidney. This is the first part of the nephron where water is reabsorbed back into the bloodstream.
proximal convoluted tubule
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.
Within the nephron (the functional unit of the kidneys), filtration occurs in the glomerolus. The filtered fluid is called filtrate. Reabsorption of filtrate occurs in a few places within the nephron, however, the majority of reabsorption takes place in the proximal convoluted tube. It is important to mention that additional reabsorption occurs in the Loop of Henle, distal convoluted tube, and the collecting ducts as well. Again, however, MOST reabsorption of filtrate from the glomerolus takes place in the proximal convoluted tube of the nephron.
Between tubular elements and vascular elements of the nephron beginnings with the proximal convoluted tubule and continuing at least part way into the distal tubule.

The limiting factor for the reabsorption of most actively transported solutes in the proximal tubule is the number of transport proteins available on the apical membrane of the tubular cells. If there aren't enough transport proteins present, the reabsorption of solutes will be limited, leading to decreased efficiency in solute reabsorption.
Most nutrient reabsorption occurs in the small intestine, particularly in the jejunum and ileum. These sections of the small intestine have specialized cells that absorb nutrients such as sugars, amino acids, and vitamins from digested food into the bloodstream for distribution to the rest of the body.
The proximal tubule is the site of most reabsorption via glucose transporters (reabsorb 100% of glucose in healthy individuals), approx. 65% Sodium and various other solutes are also reabsorbed.
