Human Heart Anatomy Diagram - Arteries and Veins Labeled #1203220 (License: Personal Use)

This detailed medical illustration depicts the human heart with major vessels clearly distinguished: red vessels represent arteries carrying oxygenated blood (e.g., aorta), while blue vessels indicate veins returning deoxygenated blood (e.g., superior/inferior vena cava, pulmonary veins). The diagram includes the pulmonary artery, left and right atria, ventricles, and coronary circulation on the heart surface. It’s designed for clarity in educational and clinical contexts.

Used on anatomy learning pages, medical school resources, health education sites, and patient information portals; targets users seeking visual understanding of cardiac circulation and structure.
