Complete Human Digestive System - Anatomically Accurate 3D Model Low-poly 3D model

This 3D model presents a scientifically accurate, high-detail representation of the complete human digestive system, showcasing the entire 30-foot gastrointestinal journey from mouth to rectum. Designed for medical, educational, and professional visualization, this model includes the oral cavity with teeth and tongue, a realistically modeled esophagus, and a stomach with J-shaped structure including the fundus and antrum. The small intestine is segmented into duodenum, jejunum, and ileum, while the large intestine features haustra and clearly distinguished ascending, transverse, descending, and sigmoid colon sections.

Accessory organs are precisely integrated, showing the liver with its lobes and bile duct system, the gallbladder tucked beneath the quadrate lobe, and the pancreas with clearly depicted exocrine and endocrine structures. The model includes ductal interconnections between liver, pancreas, and intestines, offering a comprehensive view of the digestive chemistry process.

Cross-sectional views reveal rich interior details such as villi and microvilli for nutrient absorption, gastric rugae, smooth muscle layers for peristalsis, and vascular networks for nutrient transport. The textures are photorealistic with natural coloration, including healthy pink mucosa and distinctive tissue appearances across GI segments. Proportions are true-to-life, and the intestinal coiling illustrates how over 20 feet of small intestine fit within the abdominal cavity.

Lighting and presentation are optimized for clarity and depth, using clean medical backdrops to highlight anatomical relationships. This model is ideal for anatomy instructors, healthcare professionals, app developers, and medical illustrators, offering a clear visual story of human digestion from ingestion to elimination
