Human Heart Anatomy Diagram - Educational Medical Illustration #3262833 (License: Personal Use)

This stylized anatomical illustration depicts the four-chambered human heart with the right side (blue) representing deoxygenated blood flow and the left side (red) showing oxygenated blood circulation. Major vessels-including the aorta, pulmonary artery, superior/inferior vena cava, and pulmonary veins-are clearly shown connecting to the atria and ventricles. The image emphasizes structural relationships and directional blood flow for educational clarity.

Commonly used in biology textbooks, medical training modules, health education websites, and patient-facing materials to explain cardiac anatomy and circulation. Matches user intent for visual learning, quick reference, or classroom instruction on cardiovascular physiology.
