Elimination- of waste materials. Chemical digestion can happen only if there is fluid in the stomach because enzymes in saliva react with proteins, carbohydrates, and fats found in food. These three sources of digestive enzymes ensure that everything gets digested to small molecules ready for absorption. The large intestine works as a mechanical digestion. The digestive system is a combination of organs which have been arranged together to help carry out its particular function of turning food into the energy which is necessary to survive and packaging the excess residue for waste disposal. Although there may be a tendency to think that mechanical digestion is limited to the first steps of the digestive process, it occurs after the food leaves the mouth, as well.
