Human Heart Anatomy Diagram - Medical Illustration for Education #45656 (License: Personal Use)

This medical illustration depicts the human heart with accurate positioning of the four chambers-left and right atria and ventricles-and major vessels including the aorta, pulmonary artery, and vena cava. Arteries are shown in red to indicate oxygen-rich blood flow, while blue vessels represent deoxygenated blood returning to the heart. The coronary circulation is also illustrated, emphasizing surface vasculature critical for myocardial function.

Used in educational materials, medical websites, anatomy textbooks, and patient information guides to explain cardiac structure and circulation; targets students, teachers, clinicians, and health-conscious users seeking foundational cardiovascular knowledge.
