Answer 1

$Answer:$

The mouth is the beginning of the digestive tract. In fact, digestionstarts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easilydigested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.
