The digestive system works as the food travels through each of the organs and uses bacteria to help with the digestion. The GI tract and bacteria help to break down and digest the food and liquids you eat and drink each day in order to get the nutrients. The digestive system breaks down each food into parts that are small enough to be absorbed and used by the body. Proteins are broken down by enzymes called pepsin.(NIDDK) This breaks the chemical bonds that hold the protein structures. The proteins are broken down into amino acids. Fats are broken down into fatty acids and glycerol. Carbohydrates break down into simple sugars. The large intestine absorbs water and the waste products of digestion become stool. The breaking down of foods allows our bodies to be able to use food as a source of energy. Each food gives us different amount of energy based on its structure. The digestive system works to break down food into usable nutrients. The ways in which food break down differs.
