digestive system 3d model

Create a highly detailed educational 3D model of the complete human digestive system for an interactive biology simulation. Show only digestive organs and closely related accessory digestive organs. Do not include lungs, respiratory organs, kidneys, urinary organs, reproductive organs, brain, muscles, bones, or full body anatomy except a simple transparent torso cutaway for support and positioning. The digestive system must include clearly visible and anatomically connected mouth cavity, tongue, teeth, salivary glands, pharynx, esophagus, stomach, liver, gallbladder, pancreas, small intestine, duodenum, jejunum, ileum, large intestine, colon, cecum, appendix, rectum, and anus. Organs must be correctly positioned and connected naturally from mouth to anus with realistic proportions and smooth anatomical flow. The model should use an educational medical visualization style suitable for Grade 9 to university-level anatomy learning. Make the organs colorful, clean, and visually distinct
