Human Heart Anatomy Diagram - Educational Medical Illustration #3262837 (License: Personal Use)

This vector-style medical illustration shows the four chambers of the human heart-right atrium, right ventricle, left atrium, and left ventricle-with major vessels including the aorta, pulmonary artery, superior/inferior vena cava, and pulmonary veins. Arteries carrying oxygen-rich blood are rendered in red, while veins carrying deoxygenated blood appear in blue, aiding visual learning. The clean design emphasizes structural relationships without overwhelming detail.

Commonly used in educational websites, anatomy courses, patient brochures, and health literacy resources to explain cardiac circulation and basic heart function; matches user intent for visual learning or quick reference.
