Answer:
There are 11 main parts of the digestive system including: Teeth, tongue, lips, salivary glands, esophagus, liver, pancreas, large intestine, stomath, small intestine, mouth. Other parts include epiglottis, pharynx, gallbladder, appendix, rectum, along with the diaphram, and finally, your anus (butt). I beleive you wont need any more than that.. and might actually only have to use the first 11 but.. just to make sure.
