This high-resolution medical illustration displays a sagittal section of the human heart, highlighting the four chambers (right/left atria and ventricles), the tricuspid and mitral valves, pulmonary artery, aorta, superior/inferior vena cava, and pulmonary veins. The color-coding distinguishes oxygenated (red) from deoxygenated (blue/purple) blood flow pathways. Fine details such as chordae tendineae and papillary muscles are clearly rendered to support clinical or educational understanding.
