Teeth gnash the food, breaking it down mechanically, while the three salivary glands release saliva containing the enzyme amylase, which breaks down starch and fat chemically. Saliva makes food easier to swallow by moistening it, as well as preventing the erosion of tooth enamel by modulating pH.After entering the body at the back of the throat, food travels down the esophagus, being transported not by gravity but by muscular contractions

To balance things out on the basic side, it is important that the small intestine has a high pH, because most of the enzymes used in digestion can't function properly in an acidic environment. For humans and most mammals, digestion starts in the mouth, where enzymes that aid in digestion are released in saliva and help prepare food for further digestion by the stomach and intestines

Within it, digestion is retained long enough to allow fermentation due to the action of gut bacteria, which breaks down some of the substances that remain after processing in the small intestine; some of the breakdown products are absorbed.
