anatomical heart 3d model

"Create an ultra-realistic 3D model of the human heart with full medical-grade anatomical accuracy. Include lifelike textures, natural muscle striations, realistic myocardium thickness, visible coronary arteries and veins, and detailed atria and ventricles. Show the aorta, vena cava, pulmonary arteries and veins with correct shapes and branching. Add precise valve structures (mitral, tricuspid, aortic, pulmonary) with correct leaflets. The surface should show subtle wet gloss, micro-details, and natural color variation. Make the internal chambers, septum, and vessels fully accurate for medical teaching. Present the heart in a neutral floating pose, high resolution, clean topology, and ready for animation or close-up inspection."
