saliva
the fluid released when your mouth waters
digestion
the process by which your body breaks down food into smaller nutrients
esophagus
a muscular tube that connects the mouth to the stomach
small intestine
A tube connected to the stomach where most chemical digestion and absorption take place
peristalsis
involuntary muscle contractions that push food through the digestive tract.
pancreas
produces enzymes that break down starches, protein and fat
anus
the muscular opening at the end of the rectum
teeth
bone like structures in your mouth

3 Functions of the digestive system
1. Breaks down food into molecules the body can use.
2. The molecules are absorbed into the blood and carried throughout the body
3. Wastes are eliminated from the body.
Mechanical Digestion
Begins in the mouth but most occurs in the stomach. Three strong layers of smooth muscle contract to produce a churning motion. This action mixes the food with fluids.
Chemical Digestion
Begins in mouth as enzymes in saliva turn starch into sugar, moves through stomach, most occurs in the small intestines where the liquid mixes with enzymes and secretions.
