Human Heart Anatomy Diagram - Educational Medical Illustration #3596500 (License: Personal Use)

This medical illustration depicts the human heart with red representing oxygenated blood pathways (e.g., aorta, pulmonary veins) and blue indicating deoxygenated flow (e.g., vena cava, pulmonary artery). Coronary arteries are shown branching across the surface, and internal chambers-including left/right atria and ventricles-are clearly demarcated. The image balances simplicity with anatomical fidelity for educational use.

Commonly used in biology textbooks, online health education platforms, and medical training modules to teach cardiac structure and circulation; targets learners seeking foundational knowledge of human cardiovascular anatomy.
