Mixed digestion is more efficient than either mechanical or chemical digestion alone because certain minerals present in food particles can be dissolved by acidic fluids produced by stomach cells in response to eating meat products. As the food passes through the stomach, some large particles may be removed by gastric juices contained within the stomach wall. Further, saliva also contains lysozyme, an enzyme that kills infective bacteria. These three are what help make the food moist and small enough to be swallowed. Saliva produced from three pairs of salivary glands moistens the food. These chemicals change the structure of some components of the eaten food, allowing other digestive juices to break them down further. These are mechanical and chemical digestion.
