Human Kidney Anatomy Diagram - Medical Illustration for Education #1985438 (License: Personal Use)

This black-and-white line drawing depicts a cross-section of a human kidney, clearly delineating the outer cortex, inner medullary pyramids, renal papillae, minor and major calyces, renal pelvis, and the emerging ureter. Fine stippling indicates tissue density, while radial lines in the pyramids suggest tubular structures like collecting ducts. The illustration emphasizes functional anatomy relevant to urine formation and excretion.

Used in medical textbooks, online anatomy courses, patient education materials, and clinical presentations to explain kidney structure and function; matches user intent for learning or teaching nephrology basics.
