To do its job, the system requires the cooperation of a number of different organs throughout the body, including the mouth, stomach, intestines, liver and  gallbladder. Ingestion: . The in take of food into the digestive tract through the mouth. Mechanical Processing: . The physical manipulation of solid foods into materials that are easier to propel through the digestive tract. Also increases the solid foods surface area which makes them more susceptible to enzyme activity and easier to absorb. . Science and Mathematics Education Research Group.
