This medical illustration depicts the human heart with accurate representation of the aorta, pulmonary artery, superior/inferior vena cava, and coronary circulation. Red vessels indicate oxygen-rich blood flow, while blue vessels show deoxygenated blood returning to the heart. The structure emphasizes the four chambers and key vascular connections essential for cardiovascular physiology education.

Used in medical textbooks, online anatomy courses, patient education materials, and health websites to explain cardiac structure and circulation; targets learners, clinicians, and curious users seeking foundational cardiovascular knowledge.
