It mechanically chews it, making the particles smaller and easier to chemically digest.
The teeth in mouth in the digestive system are where food is crushed physically.
The Digestive System is a human organ system consisting of the stomach, intestines, and the mouth. It begins in the mouth where the salavary glands release salivia into the mouth to break down the chemicals in the food. Your teeth physically break down the food. Then you swallow and begins stage two of digestion.
Mechanical and chemical digestion both occur in the mouth (physically chewing and when saliva breaks down food into smaller bits).
The teeth (in the mouth) - for chewing, and the muscles around the gut - for peristalsis.
The digestive system starts at the mouth.
The first task of the digestive system is to break down food into a fine pulp (mechanical digestion). When the food is physically 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.(Google)
