Human Heart Anatomy Diagram - Labeled Chambers, Valves & Blood Vessels #1203183 (License: Personal Use)

This educational diagram displays the human heart in anterior view with 15 numbered components, using color coding to distinguish oxygenated (red) from deoxygenated (blue) blood pathways. Key features include the superior and inferior vena cava (1, 2), right and left atria (3, 10), right and left ventricles (4, 12), pulmonary artery (7), aorta (15), and heart valves (6, 11, 13, 14). Arrows indicate direction of blood flow through the circulatory system.

Used in biology and medical education contexts-textbooks, online learning modules, classroom presentations-to teach cardiac anatomy and physiology. Matches user intent for visual reference, study aid, or lecture material on the cardiovascular system.
