Osmosis video - Tubular reabsorption of glucose

Tubular reabsorption of glucose is an important process that occurs in the kidneys to maintain normal blood glucose levels. When blood is filtered through the glomeruli in the kidneys, glucose is freely filtered into the tubular fluid of the nephron. In a healthy individual, nearly all of this filtered glucose is reabsorbed back into the bloodstream through the proximal tubule of the nephron. The reabsorption of glucose is facilitated by glucose transporters, primarily SGLT2 and SGLT1, which move glucose from the tubular fluid into the cells and then into the bloodstream.
