The human digestive system is a complex series of organs and glands that processes food. In order to use the food we eat as energy , our body has to break the food down into smaller molecules that it can process; it also has to excrete or get rid of 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.
