anatomical heart 3d model

Create an ultra-realistic, scientifically accurate 3D anatomical model of an adult sparrow (Passer domesticus) heart. Do NOT use human or generic mammalian heart anatomy. Reproduce the compact, elongated, conical avian heart with a pointed apex and anatomically correct anterior, posterior, superior, inferior and lateral surfaces. Include four chambers: right atrium, left atrium, right ventricle and a very thick-walled left ventricle. Accurately model the muscular right atrioventricular valve unique to birds, the left atrioventricular valve, interventricular septum and ventricular myocardium. Include the right-sided systemic aortic arch, pulmonary trunk, right and left pulmonary arteries, pulmonary veins, right and left cranial vena cava and caudal vena cava. Preserve realistic vessel origins, branching, diameters and attachment positions. Add subtle coronary vessels on the external myocardium. Use realistic biological tissue: dark red myocardium, slightly lighter atria, red oxygenated
