Human Heart Anatomy Diagram - Chambers, Valves & Blood Flow Explained #1664326 (License: Personal Use)

This black-and-white medical diagram depicts the human heart’s internal structure, including the four chambers (right atrium, right ventricle, left atrium, left ventricle), valves (tricuspid, pulmonary, mitral, aortic), and connected vessels (aorta, pulmonary artery, vena cavae, pulmonary veins). Arrows indicate the direction of blood flow-from body to right heart, lungs to left heart, and out to systemic circulation. Labels 1-19 correspond to specific anatomical features for educational reference.

Used in medical education, biology textbooks, health websites, and e-learning platforms to teach cardiovascular anatomy and physiology; targets students, educators, and healthcare professionals seeking visual reinforcement of circulatory system concepts.
