Human Heart Anatomy Diagram - Labeled Cardiovascular Structure #139641 (License: Personal Use)

This medical illustration depicts the human heart with accurate representation of the four chambers-left and right atria and ventricles-and major vessels including the aorta, pulmonary artery, superior/inferior vena cava, and pulmonary veins. Red vessels indicate oxygen-rich blood flow, while blue vessels represent deoxygenated blood, clarifying systemic and pulmonary circulation pathways. The image is ideal for teaching cardiovascular physiology and anatomy.
