This anatomical illustration depicts the human heart in anterior view, featuring the four chambers (left/right atria and ventricles), major vessels including the aorta, pulmonary artery, superior/inferior vena cava, and coronary arteries. Red vessels indicate oxygen-rich arterial circulation, while blue represents oxygen-poor venous return. The image uses color-coding and clean linework to aid in teaching cardiovascular physiology.

Commonly used in educational websites, medical textbooks, and health blogs to explain cardiac structure and circulation; serves users seeking basic or intermediate understanding of heart anatomy for study, patient education, or clinical reference.
