Question

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)

Answer 1

Answer:

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.
