All Aboard â The Digestive Process Starts in the Mouth. Digestive enzymes dwell in our mouth, where our saliva, containing an enzyme called amylase, acts as a catalyst in breaking down food and begins the process of digestion. This enzyme, also found in the pancreas, starts breaking down starches, or complex carbohydrates, into simple sugars.
This chewing reduces the size of the food particles and mixes them with saliva for easier swallowing. Before your food passes from the mouth and down your esophagus, salivary amylase, an enzyme in saliva, begins to digest the starch in your bread. That is the start of chemical digestion. The mass of chewed sandwich is called a bolus. You voluntarily swallow it, but the rest of the digestion-absorption process is involuntary. The passage of the bolus through the esophagus to the stomach occurs by peristalsis, a series of wave-like muscle contractions.
