The Digestive Process: Digestion Begins in the Mouth. The digestion process begins by the secretion of saliva even before the food reaches the mouth when stimulated by thought-of-food or smell-of-food or feel-hungry. Large food molecules (for example, proteins, lipids, nucleic acids, and starches) must be broken down into subunits that are small enough to be absorbed by the lining of the alimentary canal. These secretions vary in composition, but typically contain water, various enzymes, acids, and salts. For example, the whole digestion process involves chemical reaction of acids and the food.
