-2.0 points
Answer Key
Specific parts of the
GI tract
include the mouth, esophagus, stomach, small intestine, large intestine and rectum. Other organs such as
the liver, gallbladder and pancreas aid in digestion but are not considered part of the
GI tract
2. Explain the symptoms of diverticulosis.
Weakened areas of the large intestine that develop small pouches that push out of the
weakened areas. Happens naturally as we age. Considered non-problematic.
Becomes a problem when food gets stuck in the pouches and become inflammed and/or
infected.
When this occurs it is known as divirticulitis.
Answer Key
Explain the symptoms of diverticulosis.
Diverticulosis is weak spots in the colon that results in the formation of small pouches. When
inflamed the pouches are referred to as diverticulitis.
3. 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.

esophageal sphincter - valve/circular muscle located at the end of the esophagus and
beginning of the stomach. 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.
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
4. Name the 4 organs that are not part of the GI tract but aid in digestion.
1. Salivary glands
2. Liver
3. Gallbladder
4. Pancreas
All considered accessory organs because they secrete enzymes and hormones that
contribute to the digestion and elimination process.
