anatomical heart 3d model

"A precise 3D coronal cross-section of an avian bird heart showing fine internal chambers and textures. Distinct four-chambered structure: thin-walled right atrium and thick left atrium separated by an interatrial septum; an extremely thick, massive left ventricle forming the conical apex, with deep trabeculae carneae and fine bicuspid mitral valve with delicate chordae tendineae. The right ventricle wraps crescent-like around the septum with a unique avian right atrioventricular valve designed strictly as a smooth, heavy muscular flap with no chordae tendineae. Complete solid interventricular septum preventing blood mixing. Superior vessels reveal the pulmonary trunk arising from the right ventricle and the defining right systemic aortic arch curving rightward from the left ventricle. Dual cranial superior venae cavae enter the right atrium. Photorealistic organic muscle tissue, clear lumens, labeled internal anatomy, cinematic studio medical render."
