Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #3302232 (License: Personal Use)

This anatomical illustration depicts the four chambers of the heart (right atrium, right ventricle, left atrium, left ventricle), key valves (tricuspid valve), and major vessels (aorta, pulmonary artery, superior/inferior vena cava, pulmonary veins). Arrows indicate deoxygenated blood entering the right side and oxygenated blood exiting via the aorta from the left ventricle. The diagram emphasizes functional circulation pathways and structural relationships.

Used in educational settings such as biology or medical courses, health websites, and patient education materials to explain cardiac structure and systemic/pulmonary circulation; matches user intent for visual learning and quick reference.
