Human Heart Anatomy Diagram - Educational Medical Illustration #3596541 (License: Personal Use)

This stylized anatomical illustration depicts the human heart with prominent great vessels-including the aorta, pulmonary artery, superior/inferior vena cava, and pulmonary veins-color-coded to distinguish oxygenated (red) from deoxygenated (blue) blood. The coronary arteries and veins are shown branching over the myocardial surface, embedded in epicardial fat (yellow). The image emphasizes structural relationships critical for understanding cardiac circulation and function.

Used in medical education, health websites, biology textbooks, and patient-facing materials to explain heart anatomy, circulation, or cardiovascular conditions; matches user intent for visual learning, study aids, or clinical reference.
