Human Heart Anatomy Diagram - Labeled Cardiovascular Structure #231116 (License: Personal Use)

This medically accurate illustration depicts the human heart with clearly differentiated structures: red vessels indicate oxygenated blood flow (e.g., aorta), blue vessels show deoxygenated flow (e.g., vena cava, pulmonary artery), and yellow fat tissue surrounds the coronary arteries. The image emphasizes the four chambers, valves, and major vascular connections essential for understanding cardiovascular physiology.

Used in educational materials, medical textbooks, health websites, and patient education tools to explain cardiac anatomy, circulation, or conditions like coronary artery disease; matches user intent for learning or visual reference.
