Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
The mouth is an important part of the digestive system simply because without it, the process of digesting food will not work. The mouth is the first part of the digestive process wherein you chew or drink and then swallow.
