Human Heart Anatomy Diagram - Blood Flow, Chambers, and Valves Explained #3283142 (License: Personal Use)

The image depicts a cross-section of the human heart with color-coded regions: blue for deoxygenated blood pathways (right atrium and ventricle), red for oxygenated blood (left atrium and ventricle), and pink for myocardial tissue. Arrows indicate unidirectional blood flow through the tricuspid, pulmonary, mitral, and aortic valves, while major vessels-including the superior/inferior vena cava, pulmonary arteries/veins, and aorta-are clearly shown. Structural features like chordae tendineae and papillary muscles are also visible.
