Heart

Anterior or frontal view of an anatomical human heart shown externally, isolated against a plain background. Depict a deep red to reddish-brown muscular organ with a broad superior base, smaller rounded atrial region or atrial appendages above, larger fuller ventricles below, and a pointed conical apex directed downward and slightly to the left. The four chambers are suggested by natural external contours, subtle surface grooves, or an anterior/interventricular groove rather than an opened cutaway. Major great vessels emerge from the superior aspect as short stumps or simplified curved segments, including the aorta or aortic arch and pulmonary trunk, with some visible coronary vessels on the anterior surface. Show natural right-left asymmetry, smooth surface texture, subtle anatomical shading, and a clean educational appearance.
