Which nutrients digestion starts in the mouth?
A digestive enzyme in saliva called amylase (pronounced: AH-meh-lace) starts to break down some of the carbohydrates (starches and sugars) in the food even before it leaves the mouth.
Which nutrients are digested in the mouth and stomach?
The digestive process
| Organ | Movement | Food Particles Broken Down |
|---|---|---|
| Mouth | Chewing | Starches, a type of carbohydrate |
| Esophagus | Peristalsis | None |
| Stomach | Upper muscle in stomach relaxes to let food enter, and lower muscle mixes food with digestive juice | Proteins |
| Small intestine | Peristalsis | Starches, proteins, and carbohydrates |

How does saliva help the body digest food?
Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb.
Where does mechanical and chemical digestion take place?
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.
