Which structure is NOT part of the nephron?

Explanation:
A clear way to think about this is the nephron as the kidney’s functional unit, with components dedicated to filtration and reabsorption: the glomerulus, proximal tubule, loop of Henle, distal tubule, and collecting duct. Everything inside this tubular system handles making and refining urine. The renal pelvis sits outside of that tubular network. It’s the funnel-shaped part of the kidney’s collecting system where urine from the calyces converges before moving into the ureter. So, renal pelvis is not part of the nephron; it belongs to the kidney’s collecting system after the nephron has finished its work.
