Create a highly realistic anatomical human heart as a watertight 3D model for 3D printing. Match the provided reference image as closely as possible in overall shape, proportions, and surface detail. The heart is shown as a clean medical specimen: realistic organic form with visible coronary grooves and subtle surface wrinkles, large aortic arch at the top, pulmonary artery and vessels visible as short tubular openings on the upper right. No surrounding anatomy, no blood vessels extending beyond the main visible stubs. Neutral pose, centered, front three-quarter view similar to the reference.

3D print requirements: single solid object, manifold/watertight, no holes, no non-manifold edges, no thin fragile spikes; minimum wall thickness 2.5–3 mm where applicable; preserve major forms and grooves but avoid ultra-thin membranes. Output should be a clean high-poly sculpt suitable for printing, with details as real geometry (not only textures).

CIRCUIT 3 — Coronary Circulation

Domestic cat coronary circulation, Felis catus. Heart surface labeled: left coronary artery (paraconal interventricular branch, left circumflex), right coronary artery (subsinuosal branch), coronary sinus, cardiac veins. Arteries red, veins blue, myocardium semi-transparent, 3/4 anterior view, veterinary medical illustration.

Create a realistic anatomical 3D model of a full human heart designed specifically for 3D printing. The overall size should be approximately 80 mm in total height (about a 40 mm radius scale). The model must be completely hollow inside, with a uniform wall thickness of exactly 3 mm across the entire surface. The interior should be entirely empty, with no internal chambers, valves, or trabeculae structures. Ensure the mesh is fully watertight, manifold, and free of non-printable geometry.

Include accurate external anatomical features such as the left and right ventricles, left and right atria (external shape only), apex, and a simplified coronary sulcus. Add the major great vessels: aorta, pulmonary trunk, superior vena cava, and inferior vena cava. These vessels should be short hollow cylindrical extensions (approximately 10–15 mm long) and connected directly to the internal cavity.

Do not include microvasculature or fine coronary arteries. Maintain smooth curvature and clean topolog

Create a highly realistic, anatomically accurate 3D model of a human heart, cut cleanly into half using a sagittal section to reveal the internal structure. The model must include all four chambers: right atrium, right ventricle, left atrium, and left ventricle, with correct proportions, wall thickness, and spatial orientation. Clearly model all valves with accurate shapes and placement, including the tricuspid valve, mitral (bicuspid) valve, pulmonary valve, and aortic valve, along with chordae tendineae and papillary muscles. Include major vessels such as the aorta, pulmonary artery, pulmonary veins, and superior and inferior vena cava with correct entry and exit points. Surface should have realistic organic curvature, subtle irregularities, and medical-grade detail. Interior should be cleanly visible with precise anatomical fidelity. Use smooth topology suitable for high-resolution rendering and 3D printing. Ensure scale realism, clean mesh, and watertight geometry.
