About Digestion in Humans
- Digestion begins in the mouth where teeth break the food into smaller pieces.
- It continues in the stomach where chemicals known as enzymes are added to break down large molecules into smaller ones.
- Digestion then continues in the small intestine where large molecules continue to be broken down.
- Finally, when the molecules are small enough, the small intestine absorbs the nutrients into the blood stream.
