Human Heart Anatomy Diagram - Educational Medical Illustration #3224412 (License: Personal Use)

This stylized medical illustration shows the human heart in anatomical position, with pulmonary and systemic vessels clearly distinguished by color-blue for deoxygenated blood returning via veins, red for oxygenated blood carried by arteries. The image includes the aorta, pulmonary trunk, superior/inferior vena cava, and branching vasculature to emphasize circulation pathways. Designed for clarity and educational use, it avoids excessive detail while preserving structural accuracy.

Used in biology textbooks, online health education platforms, medical training modules, and patient-facing materials to explain cardiac structure and blood flow. Matches user intent for visual learning, anatomy reference, or introductory cardiology content.
