Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #55556 (License: Personal Use)

This high-resolution medical illustration depicts the four chambers of the human heart (left and right atria and ventricles), key valves-including the tricuspid and mitral (bicuspid)-and major vessels such as the superior/inferior vena cava, pulmonary arteries/veins, and ascending aorta. Arrows indicate the direction of blood flow: deoxygenated blood enters the right atrium, passes to the right ventricle, is pumped to the lungs via pulmonary arteries, returns oxygenated to the left atrium, then moves to the left ventricle before being ejected into the systemic circulation via the aorta. The diagram emphasizes functional anatomy for teaching cardiovascular physiology.

Used in medical education websites, anatomy textbooks, health blogs, and patient education portals; serves users seeking visual understanding of cardiac structure and hemodynamics-especially students, healthcare trainees, and patients researching heart conditions.
