Human Heart Anatomy Diagram - Labeled Cardiovascular Structure #1312676 (License: Personal Use)

This medical illustration depicts the human heart in anterior view, with the right and left atria and ventricles clearly differentiated. Red vessels represent oxygenated blood pathways (e.g., aorta, pulmonary veins), while blue vessels indicate deoxygenated flow (e.g., vena cava, pulmonary artery). The coronary arteries and branching vasculature are shown wrapping the heart surface for myocardial perfusion.

Used in educational materials, healthcare websites, anatomy textbooks, and patient brochures to explain cardiac structure and circulation; matches user intent for learning basic cardiovascular anatomy or preparing for medical exams.
