bird heart 3d model

"A hyper-realistic, medical-grade scientific internal 3D model of an avian (bird) heart cross-section. The model clearly exposes all four chambers with complex, deep red muscle textures. It must feature the defining Right Systemic Aortic Arch curving to the bird's right side, and prominent Brachiocephalic Trunks arising from it. Focus on the specialized muscular flap of the Right Atrioventricular Valve (no chordae tendineae) and the delicate bicuspid mitral valve with fine chordae tendineae in the extremely thick-walled left ventricle. Show complete interventricular and interatrial septa, pulmonary trunk, and pulmonary veins connections. Standardized blue and red arrows trace the blood flow path throughout the entire internal structure. High polygon count, clean topology, dramatic cinematic lighting."
