DIGESTIVE SYSTEM
Which of the following does not contribute to that digestion of proteins? Amylase.
Short chain triglycerides, found in food such as butterfat molecules in milk are split by a specific
enzyme in preparation for absorption. Which of the following enzymes is responsible? Lipase.
What is one main function of the small intestines? Absorption of nutrients.
Where does protein digestion begin? Stomach.
Which of the following is not a function of cholecystokinin (CCK)? Increase production of
stomach acid.
Which of the following is not a characteristic of the large intestines? It is longer than the small
intestines.
The bolus is liquefied in the stomach, and it is now called chyme.
Bile salts break up the fat globule into smaller fat droplets. This role of bile salts is best
described as lipid emulsification.
Which one of the following represents the correct order through which food passes in the
alimentary canal? Mouth, pharynx, esophagus, stomach, small intestine, large intestine.
Digestion is primarily controlled by the parasympathetic division of the autonomic nervous
system.
Gastric juice can build up from the stomach into the esophagus and cause heartburn. What
sphincter, weakened by a hiatal hernia, can contribute this condition? Cardio esophageal
Sphincter (lower esophageal sphincter)
Chemical digestion reduces large complex molecules to simpler compounds by the process of
catabolism.
All but one of the following is a function of the low pH found in the stomach. Select the
description below that does not reflect the role of the stomach acid. The stomach acid
catabolically breaks down food stuffs in preparation for absorption.
Generally, the hormones secretion and cholecystokinin which are released by duodenal
enteroendocrine cells will increase the release of digestion enzymes and bile.
Which of the following is continuous with the esophagus? Laryngopharynx.
What organ stores bile when food digestion is not occurring? Gallbladder.
