Human Heart Anatomy Diagram - Labeled Structure and Circulation Pathways #1203199 (License: Personal Use)

This medical illustration depicts the human heart in anterior view, clearly labeling the four chambers (left/right atria and ventricles), major vessels including the aorta, pulmonary artery, superior/inferior vena cava, and pulmonary veins, as well as surface coronary arteries and fat deposits. The color-coding distinguishes oxygen-rich (red) from oxygen-poor (blue) blood flow, aiding in understanding systemic and pulmonary circulation. The image also shows valve positions and cardiac muscle texture for clinical and educational context.

Used in medical textbooks, online anatomy courses, healthcare training modules, and patient education materials to explain cardiac structure, function, and pathologies like coronary artery disease or congenital defects; matches user intent for learning or teaching cardiovascular anatomy.
