Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #3789929 (License: Personal Use)

The diagram highlights deoxygenated blood entering via the superior and inferior vena cava into the right atrium, passing through the tricuspid valve to the right ventricle, then pumped through the pulmonary valve into the pulmonary artery for oxygenation. Oxygen-rich blood returns via pulmonary veins to the left atrium, flows through the mitral valve into the left ventricle, and exits via the aortic valve into the aorta for systemic circulation.
