- Food is passed to the stomach by the esophagus
- Anus opens to allow elimination
- Cells lining the intestines absorb most nutrients into the blood and lymph
- Stomach churns, mixes and grinds food to a liquid mass, while adding acid, enzymes and fluid
- Colon reabsorbs water and minerals
- Colon passes the remaining waste to the next part of the digestive tract
- Food is chewed and mixed by the mouth
- Rectum stores waste prior to elimination
- Small intestine secretes enzymes that digest carbohydrates, fat and protein
