Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #1203510 (License: Personal Use)

The diagram depicts the right and left sides of the human heart, highlighting the right atrium and ventricle receiving deoxygenated blood via the superior and inferior vena cava, and the left atrium and ventricle pumping oxygenated blood through the pulmonary veins and aorta. Arrows indicate unidirectional blood flow regulated by the atrioventricular (tricuspid and mitral) and semilunar (pulmonary and aortic) valves. The illustration uses color-coding (blue for deoxygenated, red for oxygenated blood) and precise labeling for educational clarity.

Used in medical education, biology textbooks, health websites, and patient-facing resources to teach cardiovascular anatomy and function; matches user intent for learning or reviewing heart structure and circulation.
