Verified step by step guidance

Understand the anatomy of the kidney: The kidney is divided into several regions, including the renal cortex (outer layer), renal medulla (inner layer), renal pyramids, renal pelvis, and renal calyces.

Learn the structure of a renal pyramid: Renal pyramids are triangular structures located in the renal medulla. They consist of tubules that transport urine from the nephrons to the renal pelvis.

Identify the base of the renal pyramid: The wide base of the renal pyramid faces outward toward the renal cortex, while the apex (papilla) points inward toward the renal pelvis.

Clarify the relationship between the renal pyramid and the renal cortex: The renal cortex is the outer region of the kidney, and it lies adjacent to the base of the renal pyramid. This proximity allows for the exchange of substances between the nephrons in the cortex and the tubules in the pyramid.

Conclude that the wide base of the renal pyramid lies next to the renal cortex, based on anatomical positioning and functional relationships within the kidney.
