Acts as a gate keeper and prevents anything that has moved from the esophagus into the stomach, from coming back into the esophagus. This is important because the stomach is very acidic and if any contents from the stomach go back into the esophagus, the lining of the esophagus could get burned from the acid. ileocecal sphincter - valve/circular muscle located at the end of the small intestine and beginning of the large intestine. Acts as a gate keeper and prevents anything that has moved from the small intestine into the large intestine, from coming back into the small intestine. This is important because we do not want any matter formed in the large intestine (feces) to go back into the small intestine and contaminate it. It is also important to keep most of the material in the small intestine before entering the large intestine so many nutrients can be absorbed and proper digestion and absorption can occur. Answer Key Sphincters play an important role in the GI tract. Name two sphincters discussed in the module and using your own words, briefly describe their functions. The esophageal sphincter prevents the contents of the stomach from reentering the esophagus. The pyloric sphincter controls the release of chyme into the small intestines from the stomach. The ileocecal sphincter prevents the contents of the large intestine from entering the small intestine. 4. Name the 4 organs that are not part of the GI tract but aid in digestion. 1.
