In the digestive system food is broken down into its smaller components. These small components are absorbed by the digestive system, passing into the blood. Once blood-bourne these molecules are carried across the whole body, to cells in need. The cells absorb these molecules from the blood, and in breaking down these molecules are able to harves energy from their high energy. This reaction, respiration, is dependent upon oxygen and produces carbon dioxide, water and energy.
Once energy has been harvested from these molecules it's stored, or used in cellular processes, required to maintain the cell.
