anatomical tube 3d model

A hollow, cylindrical organic tube, slightly flattened and curved, with a soft corrugated interior surface featuring distinctive horizontal ridges and folds (rugae) running along the walls. The texture is moist, elastic, and muscular — like layered soft rubber or wet silicone with subtle ribbing. Walls are firm yet flexible, approximately 3–4mm thick. Deep pink to rose coloration, smooth glossy exterior, with a faintly ridged and folded inner lining. Subtle surface vascularity with fine branching vessels beneath the outer membrane. The tube narrows slightly at one end and widens at the other. Hyper-realistic anatomical 3D model, medical illustration style, studio lighting, transparent background
