Human Heart Anatomy Diagram - Labeled Structures for Education #3789938 (License: Personal Use)

This educational diagram highlights key cardiac structures: the right and left atria, right and left ventricles, ascending aorta, and branching coronary arteries that supply oxygenated blood to the heart muscle itself. The color-coding distinguishes oxygen-rich (red) from oxygen-poor (blue) blood pathways, aiding visual comprehension of circulation. Labels are placed for clarity without obscuring anatomy.

Used in biology classrooms, medical training modules, and health education websites to teach cardiovascular anatomy; matches user intent for learning basic heart structure or preparing study materials.
