Human Heart Anatomy Diagram - Educational Medical Illustration #3262851 (License: Personal Use)

This medical illustration depicts the human heart with accurate color-coding: red for oxygenated blood pathways (e.g., aorta, pulmonary veins), blue for deoxygenated blood (e.g., vena cava, pulmonary artery), and purple for key structures like the pulmonary trunk. The image shows the four chambers-left/right atria and ventricles-with visible myocardial texture and valve outlines, making it ideal for teaching cardiovascular physiology.

Used on educational websites, medical blogs, anatomy courses, and health resource pages to explain cardiac structure and circulation; matches user intent for learning or reviewing heart anatomy visually.
