DIGESTIVE SYSTEM
- Chewing breaks down food into smaller peices and mixes with saliva
- The chewed food then enters the esophagus, which is connected into the stomach
- In the stomach, food mixed with chemicals that break the food down and passes it it the small intestines
- More chemicals continue to break down food in the small intestines, nutrients are then absorbed into the body then passes on to the large intestines
- Water is removed from food and taken into the body from the large intestines, any remaining food that as not been digested becomes solid waste
