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.
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!).
