Human Heart Anatomy Diagram - Labeled Illustration for Education & Medical Reference #3224420 (License: Personal Use)

This educational illustration depicts the human heart with distinct color-coding: red for oxygenated blood pathways (e.g., aorta), blue for deoxygenated (e.g., vena cava and pulmonary artery), and green for coronary arteries supplying the myocardium. The right and left atria and ventricles are clearly differentiated, along with major vessels and surface vasculature. Designed for clarity, it balances anatomical accuracy with accessibility for learners.
