Food is the basic need for human survival , as well as for cells. groups of tissues work together to perform different functions in order to extract the necessary materials needed for the body from the food materials and then circulate it all over the body.

The process of extraction of materials from food is concerned mainly with the digestive system. Digestive system has the necessary enzymes and environment where the food can be broken down in to smaller parts and then circulated to other cells for making other products which are necessary for the human body.
