5% of the starches are broken down in the mouth before the food is swallowed.
your teeth and tong. as you chew your teeth crush and grind the food into small pieces, the saliva causes the food to chemically break down and your tong moves it around in your mouth to make the small ball that can be swallowed.

If the food is violently forced out of the mouth, perhaps with nausea beforehand or dry heaves afterwards, the occurrence is considered vomiting.
Saliva in the mouth makes it easier for food to be swallowed and digested.
Tongue
a bolus
Food is transformed into a small lump called a bolus through the process of chewing and mixing it with saliva in the mouth. The mechanical and chemical breakdown of food in the mouth helps form the bolus, which is then swallowed and passes through the esophagus into the stomach where further digestion occurs.
