Regions of the digestive tract | Digestive enzyme | Digestion process | substrate | End product |
Mouth | salivary gland secrete salivary amylase | Mechanical digestion of chewing | starch | maltose |
Stomach | secrete the enzyme protease | acidifies the food and chemical digestion takes place. | protein | amino acids |
Pancreas |

Il. PARTS OF THE DIGESTIVE TRACT A. ORAL CAVITY After ingestion, the physical breakdown of solid foods (mechanical digestion) begins in the oral cavity (mouth). Describe how food is mechanically digested in the oral cavity. Include a discussion of how the teeth, tongue, and saliva work together to convert solid food into a moist, semi-solid mass of food called a bolus. Example: think of how a hard, dry saltine cracker is converted into a moist ball (bolus) in the mouth...
