Teeth are present in the buccal cavity. These masticate food, that is, chew food and cut them into smaller parts that can be taken inside through the food pipe. The saliva in the mouth gets mixed with the masticated food and this ball of food is now known as the bolus. It is adviced that food should be chewed properly to avoid any indigestion. The food that gets broken into smaller pieces with saliva mixed in it, has an increased surface area and makes it easier for the digestive juices to digest the essential nutrients. Chewing properly not only gives us a better taste of the food but also helps in the digestion.
