Renal oligopeptide reabsorption

Source: Wikipedia, the free encyclopedia.

Renal oligopeptide reabsorption is the part of renal physiology that deals with the retrieval of filtered oligopeptides, preventing them from disappearing from the body through the urine.

Almost all reabsorption takes place in the

proximal tubule cell
