The first task of the digestive system is to break down food into a fine pulp (mechanical digestion). When the food is physical broken down, digestive chemicals break the food down into small molecules (chemical digestion). The mouth is the organ in which the process of digestion begins. It starts the process of mechanical digestion by grinding the food with teeth. Also in the mouth, an enzyme called salivary amylase begins to break down long starch molecules into maltose.
The process of digestion begins in your mouth. The salivary glands start to function as soon as you take the first bite of food. There are three large salivary glands and numerous smaller ones located in your mouth and throat.The larger salivary glands occur in pairs and are located on either side of your mouth.he process of digestion begins in your mouth.
