Question

Food in the mouth is broken down into small pieces by __________.

• A. tongue
• B. lips
• C. teeth
• D. saliva

Answer 1

The correct option is C

teeth

The mouth is the beginning of the digestive tract. In fact, digestion starts in the mouth as soon as you take the first bite of a meal. Teeth, which helps in chewing, breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use. The tongue is a muscle attached to the floor of your mouth that helps in the mixing of food inside the mouth. It also helps in pushing the food down into the pharynx for further digestion.
