Digestion happens in the mouth. Mastication (the action of chewing and mechanically breaking down food) triggers you're exocrine glands to excret a watery liquid called saliva.
Food contains complex substances, which the body breaks down into simpler substances that it can use. This process is called digestion. It takes place in your digestive tract or gut, which is a long tube with muscly walls that runs from your mouth to your bottom (anus). Some parts of your digestive system mash up food physically, just like a food processor. Your mouth breaks food down into chunks.
