Digestive System Digestive System Digestion is the process of changing food inside the body so that the body can use it. Without digestion our body would not be able to use the food we eat as fuel for us to live, play, and work.
Digestion takes place in our bodies in the digestive system.
The digestive system is similar to a long stretchy tube which is about 9 meters long. It acts like a wrecking machine which breaks our food down into tiny nutrients which our body uses as energy. There are many different parts of our body which help us digest food. Even before we bite our food, our digestive system is already preparing to work by producing a digestive juice called saliva from inner salivary glands. When we chew our food, our teeth break the food down into smaller pieces.
