For every system to run one needs fuel and energy. Humans get their energy from food and that is supplied by digestion system. The human digestive system is very complex and interesting too when you come to know its functioning. The digestive system starts from the mouth. Food is broken down partly by chewing it and mixed with saliva which also helps in the chewing process. This semi-solid food is then swallowed to the organs in the stomach through food pipe. There is an organ that chunks the food and mixes with the strong acid called gastric acid. This mixed food material is then passed to the small intestine where it is still broken down to further smaller molecules. This fine food is passed to the large intestine to take out the required chemicals for the body. This is waste material now and excreted from the human body.
