TNO (gastro-) Intestinal Models (“TIM”) is a system of models mimicking the digestive tract. The system was developed by TNO, the Netherlands Organisation for Applied Scientific Research. [1] The models are dynamic computer controlled multi-compartmental systems with adjustable parameters for the physiological conditions of the stomach and ...
Sketchfab users can choose to make their 3D model files available for download under Creative Commons licenses [10] or to sell them in the Sketchfab store. [12] [13] With content available for sale or download, Sketchfab is positioned as a 3D model marketplace and as a 3D printing marketplace since some models are compatible with 3D printing.

English: The gastrointestinal tract, also called the digestive tract, alimentary canal, or gut, is the system of organs within multicellular animals that takes in food, digests it to extract energy and nutrients, and expels the remaining waste.
The largest structure of the digestive system is the gastrointestinal tract (GI tract). This starts at the mouth and ends at the anus, covering a distance of about nine metres (30 ft). [1] A major digestive organ is the stomach. Within its mucosa are millions of embedded gastric glands. Their secretions are vital to the functioning of the organ.
Goblet cells secrete mucus, which lubricates the passage of food along and protects the intestinal wall from digestive enzymes. In the small intestine, villi are folds of the mucosa that increase the surface area of the intestine. The villi contain a lacteal, a vessel connected to the lymph system that aids in the removal of lipids and tissue ...
The descending and sigmoid colon are slightly smaller, with the sigmoid colon averaging 4–5 cm (1.6–2.0 in) in diameter. [14] [15] Diameters larger than certain thresholds for each colonic section can be diagnostic for megacolon. 3D file generated from computed tomography of large intestine
The digestive system has a complex system of motility and secretion regulation which is vital for proper function. This task is accomplished via a system of long reflexes from the central nervous system (CNS), short reflexes from the enteric nervous system (ENS) and reflexes from GI peptides working in harmony with each other.
