Human Heart Anatomy Diagram - Chambers, Veins, Arteries & Blood Flow #3806195 (License: Personal Use)

This anatomical illustration depicts the four cardiac chambers-right atrium, right ventricle, left atrium, and left ventricle-along with major vessels including the superior and inferior vena cava (deoxygenated blood inflow), pulmonary artery (to lungs), pulmonary veins (oxygenated blood return), and aorta (systemic outflow). Blue arrows indicate deoxygenated blood flow, red arrows show oxygenated blood movement, and bidirectional arrows highlight valve-regulated flow between chambers.

Used in medical education, physiology textbooks, online learning modules, and patient education resources to explain cardiac circulation and structural relationships; matches user intent for visual learning, exam prep, or clinical reference.
