After the teeth have taken a bite with the help of the powerful muscles of the jaw, this food must be broken down into smaller pieces before it can be safely swallowed.

The food is mixed with saliva, ultimately becoming a manageable portion called a bolus that may be moved into the pharynx before being swallowed and passing via the esophagus into the stomach. The tongue may also help with oral cleansing, keeping food from prolonged contact with the teeth.
