Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #3394372 (License: Personal Use)

The diagram highlights the right atrium and ventricle handling deoxygenated blood from the superior and inferior vena cava, while the left atrium and ventricle manage oxygenated blood from the pulmonary veins. Arrows indicate unidirectional flow regulated by the tricuspid, pulmonary, mitral, and aortic valves. Major vessels-including the aorta and pulmonary artery-are color-coded (red for oxygenated, blue for deoxygenated) to clarify systemic and pulmonary circulation.
