The functional unit of the kidney is the what?

Explanation:
The nephron is the structure that performs the kidney’s complete set of tasks. It’s the smallest unit that can carry out filtration, reabsorption, secretion, and urine concentration. The nephron includes a glomerulus, where blood plasma is filtered, and a tubular system (proximal tubule, loop of Henle, distal tubule, and collecting duct) where most reabsorption and secretion occur to shape the final urine. The glomerulus alone handles filtration but relies on the tubule portions to complete urine formation, so the nephron is the true functional unit. The renal pelvis and ureter are simply channels that transport urine after it’s formed.
