Answer:

There are two kinds of digestion:  mechanical and chemical.  Mechanical digestion involves physically breaking the food into smaller pieces.  Mechanical digestion begins in the mouth as the food is chewed.  Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva.  Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.  (An enzyme is a protein that can catalyze certain biochemical reactions).

 

The Digestive Process

Mouth

Food is chewed into smaller pieces.  Adults have 32 specialized teeth—teeth that can grind, chew, and tear different kinds of food. The tongue is an organ consisting of skeletal muscles (voluntary muscles) that move the food around the mouth to allow for efficient mechanical digestion. Salivary glands beneath and in back of the tongue secrete the saliva that allows for easier swallowing of food and the beginning of chemical digestion.

Swallowing forces the chewed food through a tubular entrance (pharynx) to the esophagus (food tube).  As food is swallowed a flap-like valve, the epiglottis, closes over the trachea (windpipe) to prevent food entering the windpipe and causing choking.
