The large intestine's main function is to remove water from the undigested matter and form solid waste that can be excreted. The tongue assists in mixing the food with the saliva and then the tongue and roof of the mouth soft palate help move the food along to the pharynx and esophagus. This more advanced type of digestion occurs in chordates, annelids, and crustaceans. The bile salts return to the lumen to repeat the process. A digestive enzyme called amylase pronounced: Villi have cells that produce intestinal enzymes which complete the digestion of peptides and sugars.

Digestive System: From Mouth to Anus
In addition to holding the food, it's also a mixer and grinder. Other than the chemical digestion of carbohydrates in the mouth, all digestion to this point has been mechanical. This is because the cracker is composed of carbohydrates, which saliva is able to digest at least partly. Saliva contains antibacterial compounds and various enzymes to aid the breakdown of food molecules. The ball of food that leaves the mouth is known as a bolus.
This enzyme only breaks down carbohydrates, not proteins. Peristalsis is not to churn, but to slowly move food along towards the large intestine, however, segmentation is the local mixing of food with enzymes and intestinal juices from pancreas etc. For digestion to occur, of course, it is necessary first to have something to digest—namely, nutrients.

On the other hand, vegetable fats, such as those in avocados and olive oil, as well as the animal fats in such fish as tuna, mackerel, and salmon can be highly beneficial. Nutrients advance through the alimentary canal to the stomach and small intestine, and waste materials continue from the small intestine to the colon large intestine and anus. Once nerves in the cheeks and tongue are stimulated by the food, they send messages to the brain, which, in turn, alerts nerves in the stomach wall, stimulating the secretion of gastric juice before the bolus itself arrives in the stomach.
