330 Review Sheet 25 17. In the procedure concerning the action of bile salts, how did the appearance of tubes 1 and 2 differ?. Explain the difference. 18. Pancreatic and intestinal enzymes operate optimally at a pH that is slightly alkaline, yet the chyme entering the duo- denum from the stomach is very acidic. How is the proper pH for the functioning of the pancreatic-intestinal enzymes ensured? 19. Assume you have been chewing a piece of bread for 5 or 6 minutes. How would you expect its taste to change during this interval? Why? Physical Processes: Mechanisms of Food Propulsion and Mixing mysing 20. Match the items in the key to the descriptive statements that follow. 1. blocks off the nasal cavity during swallowing 2. voluntary phase of swallowing 3. propulsive waves of smooth muscle contraction. .4. sphincter that opens when food or fluids exert pressure on it 5. movement that mainly serves to mix foodstuffs. 6. forces food into the pharynx 7. involuntary phase of swallowing.

Pyloric stenosis is a type of gastric outlet obstruction caused by a narrowing of the pyloric part of the stomach. It is most common in infants. Describe the clinical signs that you would expect to see with this condition. o'te saw yriw 22. Individuals with cystic fibrosis are plagued by increased production of mucus. This excess mucus has a variety of effects on the body, including decreased production of pancreatic enzymes and blockage of the pancreatic ducts that secrete enzymes. Describe how impaired pancreatic enzyme secretion affects digestion.
