The digestive system consists of a series of organs and glands that process the food we eat in order to convert food into energy. The body needs to break food down into smaller molecules that it can utilise the nutrients in food before excreting (getting rid of) the unusable components of food as waste.
Most of the digestive organs (like the stomach and intestines) are tube-like and contain the food as it makes its way through the body.
The digestive system is essentially a long, twisting tube that runs from the mouth to the anus, plus a few other organs (like the liver and pancreas) that produce or store digestive chemicals.
Without the digestive system, our bodies would not be able to get nutrients from the food we eat or get rid of the waste products that food makes and we would soon become ill!
