This anatomical illustration depicts the human heart with distinct color coding: red for oxygen-rich structures (left atrium/ventricle, aorta), blue for oxygen-poor pathways (right atrium/ventricle, pulmonary artery), and gold for the coronary arteries supplying the myocardium. Major chambers, valves, and vascular connections are clearly outlined to support learning in biology or medical contexts.

Used in educational websites, e-learning modules, medical textbooks, and health infographics to teach cardiovascular anatomy; matches user intent for visual learning, study aids, or patient education materials.
