Food is broken down in the mouth by the chewing action. Different types of teeth are involved. Some teeth MASH the food and some shred the food. Te purpose is to make the food pieces smaller and increase the amount of surface area of food that are exposed to saliva and stomach juices to speed the digestive process.
