Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #2367982 (License: Personal Use)

This medical illustration depicts the four chambers of the human heart-right atrium, right ventricle, left atrium, and left ventricle-along with key valves (tricuspid, pulmonary, mitral, aortic) and major vessels (superior/inferior vena cava, pulmonary arteries/veins, aorta). Blood flow direction is indicated by arrows, distinguishing oxygenated (red) and deoxygenated (blue) circulation pathways. The diagram serves as a foundational visual aid in cardiovascular education.

Used in medical textbooks, online anatomy courses, healthcare training modules, and patient education materials to explain cardiac structure and function; matches user intent for learning or teaching human circulatory system basics.
