Human Heart Anatomy Diagram - Chambers, Valves, and Conduction System #1664336 (License: Personal Use)

This black-and-white medical illustration precisely labels all major components of the human heart: four chambers (right/left atria and ventricles), valves (tricuspid, pulmonary, mitral, aortic), great vessels (aorta, pulmonary artery/veins, superior/inferior vena cava), and the cardiac conduction system (SA node, AV node, His bundle, Purkinje fibers). The diagram emphasizes functional anatomy for understanding blood flow and electrical impulse propagation. It is ideal for students, clinicians, and educators seeking clarity on cardiovascular structure and physiology.

Used in medical textbooks, online anatomy courses, healthcare training modules, and patient education resources to explain heart structure and function; matches user intent for learning or reviewing cardiac anatomy and electrophysiology.
