6–37 The funnel-shaped pharynx serves as a passageway to the respiratory and GI
tracts and provides a resonating chamber for speech sounds. Use the CF pharyng/o
(throat) to construct words that mean
inflammation of the throat: ____________________ / __________
pain in the throat: ____________________ / _____ / ____________________ or
____________________ / ____________________
6–38 Food is propelled through the GI tract by coordinated, rhythmic muscle
contractions called peristalsis. (See Fig. 6–1.)
The bolus is transported to the stomach by involuntary muscle contractions known
as ____________________.
6–39 Gastr/ic juices in the stomach coupled with mechanical churning turn the
bolus into a semiliquid mass called chyme. The chyme slowly leaves the stomach and
continues the process of digestion as it enters the first part of the small intestine
(duodenum). Review Figure 6–1 to follow the digestive path of the bolus as it enters
the duodenum.
Competency Verification:Check your labeling of Figure 6–2 with the answers in Appendix B: Answer Key, page 578.
6–40 Peptic ulcer disease (PUD) is a condition in which the lining of the esopha-
gus, stomach, or duodenum is eroded, usually from infection with Helicobacter pylori
bacteria. Ulcers are named by their location: esophag/eal, gastr/ic,or duoden/al.
Peptic ulcers that occur in the small intestine are called duoden/al ulcers;peptic
ulcers that occur in the esophagus are called
____________________ / ____________________; peptic ulcers that occur in the
stomach are called __________ / ____________________.
6–41 The erosion in the lining of the esophagus, stomach, and duodenum in
PUD can also be due to an increase in the concentration of hydrochloric acid and
pepsin. As a result, the damaged mucosa is unable to secrete enough mucus to act as a
barrier against the acid, which, combined with hypersecretion of acid, creates a large
amount of acid moving into the duodenum. As a result, peptic ulcers occur more
commonly in the duodenum. Use muc/oto build a term meaning
resembling mucus:__________ / __________
pertaining to mucus:__________ / __________
6–42 Gastr/ic ulcers may cause severe pain and inflammation of the stomach. A medical
term that means inflammation of the stomachis ____________________ / __________.
PUD is the abbreviation for ____________________ ____________________
____________________.
6–43 Gastr/o/dynia is the medical term for pain in the stomach. Another term that
means pain in the stomachis ____________________ / ____________________.
