Human Heart Blood Flow Diagram - Anatomy & Circulation Explained #2367890 (License: Personal Use)

This medical illustration details the complete circulatory pathway through the human heart: deoxygenated blood enters via the superior and inferior vena cava into the right atrium, flows to the right ventricle, then to the pulmonary arteries for lung oxygenation. Oxygen-rich blood returns via pulmonary veins to the left atrium, passes into the left ventricle, and is pumped through the aorta to the body. Key structures-including atria, ventricles, valves, and major vessels-are clearly labeled with directional arrows.

Used in educational healthcare content (e.g., anatomy textbooks, medical training sites, patient education portals) to explain cardiac physiology; matches user intent for learning heart function, preparing for exams, or understanding cardiovascular conditions.
