Answer:
Digestion
Explanation:
Digestion is the process of breaking down the food particles into smaller units by chewing them and mixing them with saliva in the mouth. The digestive system in humans includes the gastrointestinal tract as well as the accessory organs of the digestion process. The food chewed down by the teeth are assimilated and absorbed by our body.
Food enters through the gastrointestinal tract where different enzymes and bile juices break down the food to be absorbed by our body. This process is called digestion process.
