anatomical heart 3d model

Hyper-realistic 3D human heart, fully modeled inside and out — splittable at any plane. Three wall layers: thin epicardium, thick fleshy myocardium with helical fiber pattern, smooth pale endocardium lining all chambers. Left ventricle walls visibly thicker than right. All four chambers internally detailed — trabeculae carneae, papillary muscles, chordae tendineae, fossa ovalis, moderator band. All four valves fully modeled — Tricuspid, Mitral, Pulmonary, Aortic — with realistic thin translucent leaflets. All coronary arteries present. Great vessels intact. Tissue must look genuinely fleshy — subsurface scattering, reddish-brown complex coloring, purplish venous regions, natural moisture sheen. Micro surface irregularities, visible muscle fiber direction. Zero plastic, clay, or cartoon quality. Medical studio lighting, dark background. Fully volumetric — not a shell. Every internal structure geometrically accurate and visible when heart is cut open.
