Human Heart Anatomy Diagram - Labeled Cardiovascular System Illustration #3224422 (License: Personal Use)

This medically accurate illustration depicts the human heart with realistic texture and color-coding: red vessels represent oxygen-rich arterial flow (e.g., aorta, pulmonary veins), while blue vessels indicate deoxygenated venous return (e.g., vena cava, pulmonary arteries). Key structures-including the left and right atria and ventricles, aortic arch, and coronary arteries-are clearly visible, supporting learning in anatomy, physiology, or cardiology contexts.

Used on educational websites, medical blogs, e-learning platforms, and healthcare provider pages to explain cardiac structure and circulation; matches user intent for visual learning, study aids, or patient education materials.
