Human Heart Anatomy Diagram - Educational Medical Illustration #3365155 (License: Personal Use)

This vibrant medical illustration depicts the human heart with accurate structural representation: red vessels indicate oxygenated blood flow (e.g., aorta), blue vessels show deoxygenated flow (e.g., vena cava, pulmonary artery), and yellow coronary arteries supply myocardial tissue. The four chambers-right and left atria and ventricles-are clearly differentiated, with visible valves and major vascular connections. The style balances scientific accuracy with accessibility for educational use.

Used in medical education websites, biology textbooks, health blogs, and patient-facing materials to explain cardiac structure and circulation; matches user intent for learning or teaching cardiovascular anatomy.
