Human Heart Anatomy Diagram - Blood Flow Through Chambers & Vessels #1690432 (License: Personal Use)

The diagram depicts the human heart’s four chambers-right atrium, right ventricle, left atrium, and left ventricle-with color-coded blood flow: blue for deoxygenated blood entering via vena cava and exiting via pulmonary artery, red for oxygenated blood returning via pulmonary veins and pumped out through the aorta. Arrows indicate direction of flow, highlighting the dual circulation system (pulmonary and systemic). Major vessels including superior/inferior vena cava, pulmonary arteries/veins, and aorta are clearly labeled by structure and function.

Used in medical education, biology textbooks, health websites, and patient information portals to explain cardiac physiology and circulation. Matches user intent for learning basic heart anatomy, understanding blood flow, or preparing teaching materials.
