The Mouth and Buccal Cavity
Food enters the buccal cavity via the mouth. In the buccal cavity, there are four different types of teeth: incisors, canines, molars, and premolars. The teeth perform chewing so that large particles of food can be broken down into smaller particles, which in turn make digestion easier for the stomach, and intestines.
The tongue has special taste buds that help us select suitable foods. Three salivary glands secrete saliva that empties into the buccal cavity. Saliva also helps in promoting digestion. Perhaps, this is the reason why parents often teach children to eat their food slowly, and chew it properly.
