Introduction:

A nephron is the functional unit of the kidney. It is a tube-like structure with enlarged terminal ends. The wall of the nephron is made of a single layer of cube-like cells, called cuboidal epithelial cells. Their ultrastructure changes depending on the function of the segment they are present in. It plays a pivotal role in several homeostatic processes, including the reabsorption of sodium chloride and potassium secretion. It also helps in maintaining the blood pressure.
