heart anatomy 3d model

A highly accurate educational 3D anatomical model of the human heart, designed specifically for medical anatomy education. Realistic human heart anatomy, adult human heart, anatomically structured, scientific medical visualization, accurate external morphology. Clearly defined: right atrium, left atrium, right ventricle, left ventricle, mitral valve, tricuspid valve, aortic valve, pulmonary valve, aorta, pulmonary trunk, superior vena cava, inferior vena cava, pulmonary veins, major coronary vessels. The model must have clean geometry and clearly distinguishable anatomical structures. Designed for interactive educational use: rotatable, zoomable, layer-based exploration, individual anatomical structures should be suitable for separation and isolation. Professional medical visualization. Realistic anatomical proportions. Clean topology. Moderate polygon count suitable for a mobile educational application. No cartoon style. No fantasy anatomy. No exaggerated proportions. No futurist
