Human Heart Anatomy - Labeled 3D Diagram for Medical Education #1821177 (License: Personal Use)

This medically accurate 3D model displays the four chambers of the heart-right and left atria and ventricles-with visible tricuspid, mitral, pulmonary, and aortic valves. Major vessels such as the aorta, pulmonary artery, superior/inferior vena cava, and pulmonary veins are color-coded (red for oxygenated, blue for deoxygenated blood) to clarify circulation pathways. The cutaway view emphasizes structural relationships critical for understanding cardiac function and pathology.

Used in medical textbooks, online anatomy courses, patient education portals, and clinical training modules; targets users seeking visual reinforcement of cardiovascular physiology or preparing for exams like USMLE or NCLEX.
