This high-resolution medical illustration depicts a sagittal cross-section of the human heart, clearly exposing the right and left atria and ventricles, the tricuspid and mitral (bicuspid) valves, and the pulmonary artery and aorta. The image also shows chordae tendineae and papillary muscles supporting valve function, along with the pericardial sac at the base. Color-coding distinguishes oxygenated (red) from deoxygenated (blue) blood pathways.
