Samples can be harvested for analysis from these models from any compartment at any time. TIM-2 simulates the colon, containing the microbiota as found in human colon. This model serves as a tool to study fermentation of non-digestible food components (fibers and prebiotics) and the release of drugs specifically targeted for the colon. [9]
Control of the digestive system is also maintained by ENS, which can be thought of as a digestive brain that can help to regulate motility, secretion and growth. Sensory information from the digestive system can be received, integrated and acted upon by the enteric system alone. When this occurs, the reflex is called a short reflex. [4]
It differs from the main body of Optimal Foraging Theory in stating that animals can select food in order to make optimal use of their digestive tract (maximize digestion rate) rather than the maximization of the food ingestion rate, which is the base of Optimal foraging theory.
The gastrointestinal wall of the gastrointestinal tract is made up of four layers of specialised tissue. From the inner cavity of the gut (the lumen) outwards, these are the mucosa, the submucosa, the muscular layer and the serosa or adventitia.
Usually, the in-gel digestion is run as an overnight process. For the use of trypsin as protease and a temperature of 37 °C the time of incubation found in most protocols is 12-15 h. However, experiments about the duration of the digestion process showed that after 3 h there is enough material for successful mass spectrometric analysis. [38]

The cephalic phase of digestion is the stage in which the stomach responds to the mere sight, smell, taste, or thought of food. About 20% of total acid secretion occurs before food enters the stomach.
At the end of the third week, the neural tube, which is a fold of one of the layers of the trilaminar germ disc, called the ectoderm, appears.This layer elevates and closes dorsally, while the gut tube rolls up and closes ventrally to create a "tube on top of a tube."
