- Anus: Opening to release wastes.
- Liver: Helps carrie away wastes and break down fats.
- Pancreas: Produces enzymes and hormones that break down food.
- Gallbladder: Stores and concentrate bile.
Digestion of Large Food Molecules
The digestion of large food molecules is essential because large foods need to be broken down into smaller pieces so absorption can occur.
Enzymes in Digestion
Enzymes are needed in digestion because enzymes are the ones that break down the food into smaller pieces and they also speed up the digestion process with normal body temperature.
