Summary Introduction
Introduction:
A nephron is the histological and functional unit of the kidney. It is a tube-like structure with enlarged terminal ends. It includes Bowman’s capsule, proximal tubules, a loop of Henle and distal tubules. It plays a pivotal role in several homeostatic processes including the reabsorption of sodium chloride and potassium secretion.
