What is the functional unit of the kidney?

Explanation:
The functional unit of the kidney is the nephron. Each nephron carries out filtration, reabsorption, secretion, and urine concentration. It begins with the glomerulus, a network of capillaries where plasma is filtered, and continues through a series of tubules—the proximal tubule, loop of Henle, distal tubule, and collecting duct—where most reabsorption and secretion occur. The nephron as a whole (not just the glomerulus) is what forms urine. The ureter is simply a tube that transports urine to the bladder, and nephrology is the medical specialty that studies kidney function and disease.
