The organs involved only in the chemical digestion of food are:
- Pancreas - It produces digestive enzymes that are released into the small intestine to aid in the chemical digestion of food.
- Liver - It produces bile, which helps in the emulsification and digestion of fats, contributing to chemical digestion.
The other organs mentioned (large intestine, stomach, esophagus, small intestine, and mouth) also play roles in mechanical digestion or have functions beyond just chemical digestion.
