Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #83232 (License: Personal Use)

This educational illustration depicts the four chambers of the heart-right atrium, right ventricle, left atrium, and left ventricle-along with the four major valves (tricuspid, pulmonary, mitral, and aortic) and principal vessels including the superior and inferior vena cava, pulmonary arteries and veins, and the aorta. Arrows indicate the path of deoxygenated blood entering the right side, oxygenation in the lungs, and oxygen-rich blood returning to the left side for systemic circulation. The diagram uses distinct colors to differentiate oxygenated (pink/red) and deoxygenated (blue/purple) blood pathways.

Used in medical education, biology textbooks, health websites, and patient-facing resources to explain cardiac anatomy and circulatory physiology; matches user intent for learning or reviewing heart structure and function.
