Human Kidney Anatomy Diagram - Labeled Cross-Section for Medical Education #3738848 (License: Personal Use)

This vintage-style engraved illustration depicts a sagittal cross-section of the human kidney, clearly distinguishing the outer cortex (labeled 2), inner medullary pyramids (5), renal columns, minor and major calyces (C), renal pelvis (D), and the emerging ureter (U). Fine hatching and stippling techniques emphasize tissue texture and structural boundaries, typical of 19th- to early-20th-century medical atlases. Labels such as A (renal artery/vein), 1 (cortex), 2′/2″ (cortical regions), and 4 (renal column) provide precise anatomical orientation.

Used in medical textbooks, anatomy courses, and online educational resources to teach renal structure and function; supports user intent for visual learning, exam preparation, or clinical reference.
