Textbook Question
Chapter 22, Problem 18CYR
Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
a. Motility of the alimentary canal is regulated by the enteric nervous system, the parasympathetic nervous system, and hormones.
b. The esophageal and pharyngeal phases of swallowing are mediated by the swallowing reflex of the brainstem and the enteric nervous system.
c. Smooth muscle of the stomach contracts when food enters from the esophagus.
d. Control of gastric emptying into the duodenum is important to allow the chyme to be neutralized and diluted by pancreatic secretions.
e. During eating, the small intestine exhibits motion in the migrating motor complex pattern.

The normal mechanism of defecation involves:A. Stretch receptors located in the duodenum and jejunum initiate a long-lasting reflex that relaxes the internal anal sphincter several hours after food initially passes from the stomach to the intestines.B. Stretch receptors located in the rectal wall initiate the defecation reflex inresponse to an incoming mass movement.C. The defecation reflex involves contraction of the rectal wall and simultaneous relaxation of the internal anal sphincter.D. Digestive fluids secreted from the pancreas and gall bladder contain enzymesthat act on the smooth muscle of the intestine, stimulating peristalsis.E. Conscious signals from the cortex will allow for relaxation of the external anal sphincter (when appropriate!).
Match the structures to the correct descriptions. Some answers may be used more than once, and some may not be used at a
Most nutrient absorption occurs here.
A. submandibular
This structure has 3 layers of smooth muscle rather than 2.
B. pancreas
Involuntary movement of this structure prevents the bolus from entering C. gall bladder
the trachea.
D. parotids
V These are the largest salivary glands.
E. large intestine
V This structure receives bile and pancreatic juice.
F. small intestine
v During digestion, most water is absorbed here.
G. liver
V This structure is important in mechanical digestion.
H. epiglottis
V This structure produces digestive juice and enzymes that breakdown all
types of maeromolecules.
1. glottis
J. stomach
This structure compacts the indigestible remains of digestion.
V This structure produces bile.
v This structure creates chyme.
There are two different kinds of secretions associated with the digestive system that needs to be understood to avoid confusion when describing how the digestive system functions.
Which one of these secretions will be involved in the control of digestion through the blood?
A.Endocrine
B.Exocrine
