- Pancreas - produces pancreatic juice which contain digestive enzymes
- Liver - produces bile for the emulsification of fat
- Stomach - serves as a temporary store of food and produces digestive juices
- Small intestine - functions in food digestion
- Large Intestine - helps to remove undigested food from the body
Therefore, the organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.
