Human Heart Anatomy Diagram - Labeled Cardiovascular Structure #1203184 (License: Personal Use)

This anatomical illustration depicts the human heart with major vessels clearly distinguished: red for oxygenated blood in arteries (e.g., aorta) and blue for deoxygenated blood in veins (e.g., superior/inferior vena cava). Key structures such as the pulmonary artery, pulmonary veins, and atria/ventricles are visible, supporting cardiovascular education. The simplified yet accurate style makes it ideal for introductory biology or health science contexts.

Used on educational websites, medical training portals, and K-12 or college anatomy pages; serves users seeking visual understanding of heart structure and blood flow for study, teaching, or patient education.
