Human Heart Anatomy Diagram - Labeled Chambers, Valves & Blood Flow #1498726 (License: Personal Use)

This black-and-white anatomical sketch depicts the human heart in anterior view with internal chambers (right and left atria and ventricles) clearly delineated using stippling. Major vessels-including the aorta, pulmonary artery, and superior vena cava-are shown, with red and purple lines indicating oxygenated and deoxygenated blood flow paths through valves and chambers. The illustration emphasizes structural relationships critical for understanding cardiac physiology.

Used in medical textbooks, anatomy courses, health education websites, and patient-facing resources to explain heart structure and circulation; matches user intent for learning or reviewing cardiovascular anatomy.
