There are two types of digestion: mechanical and chemical.
Explanation:
Mechanical digestion involves the mechanical breaking down of food into smaller pieces. It begins in the mouth with chewing. The tongue and the teeth play the most important roles here in moving the food around and chewing.
Chemical digestion involves the chemical breakdown of food by different enzymes and chemicals. This also starts in the mouth with salivary amylase that starts the process of carbohydrate breakdown. Chemical digestion continues throughout the digestive system with gastric acid in the stomach, and pancreatic and other enzymes in the small intestine.
