The nephrons are primarily located in which region of the kidney?

Explanation:
The main idea is where the nephron—the kidney’s functional unit—spends most of its structure. The glomerulus, which is where filtration begins, sits in the renal cortex, and most of the proximal and distal tubules are also in the cortex. A subset of nephrons have long loops of Henle that reach into the medulla, but the majority of nephron components remain in the cortex (cortical nephrons make up the large majority, with only a smaller proportion having long medullary loops). The renal pelvis and ureter are part of the collecting system, not nephrons themselves. So the cortex is the region that houses most of the nephron.
