This grayscale medical illustration presents a sagittal cross-section of the human heart, clearly delineating the four chambers (right and left atria and ventricles), the septum, and major vessels including the aorta, pulmonary artery, superior and inferior vena cava. Key valves-tricuspid, pulmonary, mitral, and aortic-are precisely indicated, along with coronary arteries and conduction system landmarks. The labeling system supports learning and clinical reference in anatomy and cardiology contexts.
