Starting in the mouth, food follows a pathway through the digestive system. Describe how the mouth is involved in both mechanical and chemical digestion. (At least one paragraph)

The mouth uses both mechanical and chemical digestion. Mechanical digestion involves physically breaking down the food into smaller pieces (using the jaw/teeth). However, chemical digestion then takes over and starts breaking down the food into simpler nutrients that can be used by the cells using saliva, which is naturally made within the mouth.
