Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #275729 (License: Personal Use)

This anatomical illustration depicts the four chambers of the human heart-right atrium, right ventricle, left atrium, and left ventricle-with labeled valves (tricuspid, pulmonary, mitral, aortic) and directional arrows indicating blood flow. Deoxygenated blood enters via the superior/inferior vena cava into the right side, is pumped to the lungs via the pulmonary artery, returns oxygenated through the pulmonary veins to the left atrium, then exits via the aorta. The diagram uses distinct colors (blue for deoxygenated, red/pink for oxygenated) to enhance comprehension.

Used in medical education, biology textbooks, health websites, and patient-facing materials to explain cardiac physiology; supports learning about circulatory system function and common cardiovascular conditions.
