Human Kidney Anatomy Diagram - Labeled Cross-Section for Medical Education #3823740 (License: Personal Use)

This medical illustration depicts a sagittal cross-section of a healthy human kidney, clearly distinguishing the outer renal cortex, inner medullary pyramids, and renal pelvis. The red vessels represent the renal artery and its branches delivering oxygenated blood, while the blue vessels indicate the renal vein draining deoxygenated blood; the ureter is shown exiting the renal pelvis. The calyces collect urine from the papillae before funneling it into the pelvis.

Used in medical textbooks, anatomy courses, healthcare websites, and patient education materials to explain kidney structure and function; matches user intent for learning or reviewing renal anatomy.
