Physical intestinal function or physical digestion is the splitting down of food into small contaminants by actual procedures such as smashing and chewing. It is mainly done by using the stomach contractions, teeth, mouth and bile. For improving the surface area for chemical reactions inside the stomach and the rate of chemical reaction, it is recommended to use physical digestion techniques. The muscular churning of the food and moving the food down the digestive tract are achieved by physical digestion techniques which also include peristalsis.

Chemical digestion on the other hand refers to transforming meals into small contaminants through the enzymatic responses. Chemical substances including useful bacteria and enzymes are used to increase the rate of chemical reaction. This is achieved by breaking the chemical bonds through the hydrolysis processes. Lipases, carbohydrates and proteases are some of the most commonly used type of enzymes recommended by the doctors. These enzymes are extremely powerful and have the ability to break down proteins, carbohydrate fats and enzymes in our body. Enzymes are usually found in stomach, saliva, juices and intestinal juices, produced by the stomach glands, pancreases, salivary glands and intestinal walls inside the body’s digestion system. Direct mechanical stimulation process, hormones, reflex stimulation and expectation are some of the processes responsible for releasing these digestive enzymes from our body.
