anatomical heart model 3d

“Create a high-quality, realistic 3D model of the human heart (external anatomy only), medically accurate and educational. The model should clearly show the ascending aorta, pulmonary trunk, pulmonary arteries, superior vena cava, inferior vena cava, left and right atria, left and right ventricles, coronary arteries, and apex of the heart. Natural anatomical proportions, smooth but detailed surface, clean topology, neutral red/pink tissue color, no internal cut sections, no blood, no stylization. Designed for anatomy learning and labeling, suitable for Sketchfab viewing and Blender editing.”
