Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow #2367863 (License: Personal Use)

This medical illustration depicts a frontal cross-section of the human heart, clearly labeling the four chambers (right atrium, right ventricle, left atrium, left ventricle), the tricuspid and bicuspid (mitral) valves, papillary muscles with chordae tendineae, and major vessels including the aorta, pulmonary artery, and vena cavae. Arrows indicate the direction of blood flow through the heart, emphasizing systemic and pulmonary circulation pathways. The diagram also identifies semilunar valves at the bases of arteries and pulmonary veins returning oxygenated blood from the lungs.

Used in educational contexts such as biology textbooks, medical school lectures, online anatomy courses, and health websites to teach cardiovascular structure and function; matches user intent for learning or reviewing heart anatomy.
