This medical illustration depicts a sagittal cross-section of the human heart, clearly labeling the left and right atria and ventricles, mitral and tricuspid valves, aorta, pulmonary artery, superior vena cava, and inferior vena cava. The color-coding distinguishes oxygenated (red) from deoxygenated (blue/purple) blood flow pathways. Fine details like chordae tendineae and papillary muscles are included to support educational use in physiology and cardiology contexts.

Used in medical education, patient brochures, health websites, and biology textbooks to explain cardiac structure and circulation; matches user intent for learning anatomy, preparing for exams, or understanding heart conditions.
