Saliva moistens the food and carries dissolved food molecules to the taste buds. Figure 1. These organs break down food into bits that your body absorbs and uses for energy. These are absorbed into the enterocytes, where remaining dipeptides and tripeptides are broken down further. by Howard F. Loomis Jr., D.C. Plant enzymes are important because they are capable of digesting food before the body's own digestive process begins. Mouth. The first of these processes ingestion refers to the entry of food into the alimentary canal through the mouth.

These molecules begin digesting in the mouth and continue through the body to be used for . The chemical process of digestion begins during chewing as food mixes with saliva, produced by the salivary glands (Figure 11.5). Saliva play many functions at the beginning like it dissolve some food particles to stimulate our taste buds. Saliva contains the amylase enzymes that help to break down chemically of carbohydrates in the food. The by-products of this reaction are carbon dioxide and urine.

This is where digestive juices and enzymes break down the food that you chewed and swallowed. After the digestive process begins in the mouth with mastication and salivary enzymes, the stomach muscles break down the food into smaller particles for easier mixing with gastric juices. What are the 3 main functions of the digestive system? Once in the mouth, the teeth, saliva, and tongue play important roles in mastication (preparing the food into bolus). When food is dropping in the mouth, the tongue helps to move it around and the saliva coats, stick-together and lubricates the food for easier chewing and swallowing. The diagram of the process of chemical digestion and absorption shows the path that food takes through the digestive system.
