In the mouth and stomach, salivary α-amylase initiates the digestion of which nutrients?
a. Proteins c. Fats b. Carbohydrates d. Fiber - ✔✔ANSW✔✔..B: cabohydrates
Salivary α-amylase is an enzyme that initiates only carbohydrate digestion in the mouth
and stomach
Which elements in saliva protect against tooth decay? a. Salivary α-amylase and ptyalin
b. Secretin and IgA c. Endogenous enamelin and salivary β-amylase d. Exogenous
fluoride and a pH of 7.4 - ✔✔ANSW✔✔..D: exogenous fluoride pH 7.4
The bicarbonate concentration of saliva sustains a pH of approximately 7.4, which
neutralizes bacterial acids and prevents tooth decay. Exogenous fluoride (e.g., fluoride
in drinking water) is absorbed and then secreted in the saliva, providing additional
protection against tooth decay. Decay prevention is not associated with any of the other
options.
Saliva contains which immunoglobulin (Ig)? a. IgA c. IgG b. IgE d. IgM -
✔✔ANSW✔✔..A: IgA
Saliva contains only IgA, which helps prevent infection.
What effect is a result of inhibiting the parasympathetic nervous system with a drug
such as atropine? a. Salivation becomes thinner. c. The pH of saliva changes. b.
Salivation decreases. d. Digestive enzymes are inhibited. - ✔✔ANSW✔✔..b: salivation
decreases
The sympathetic and parasympathetic divisions of the autonomic nervous system
control salivation. Because cholinergic parasympathetic fibers stimulate the salivary
glands, atropine (an anticholinergic agent) inhibits salivation and makes the mouth dry.
None of the other options is a result of drugs such as atropine.
, Food enters the stomach via which sphincter? a. Cardiac c. Gastric b. Upper
esophageal d. Fundal - ✔✔ANSW✔✔..A: cardiac
Each end of the esophagus is opened and closed by a sphincter. The upper esophageal
sphincter (cricopharyngeal muscle) prevents entry of air into the esophagus during
respiration. The lower esophageal sphincter (cardiac sphincter) prevents regurgitation
from the stomach. The lower esophageal sphincter is located near the esophageal
hiatus—the opening in the diaphragm where the esophagus ends at the stomach. The
cardiac sphincter is the only option that fulfills the function described in the question.
Which gastric cells secrete hydrochloric acid and intrinsic factor? a. Parietal c. G b.
Chief d. H - ✔✔ANSW✔✔..A: Parietal
Of the available options, only the parietal cells (oxyntic cells) secrete hydrochloric acid
and intrinsic factor.
Which cells in the stomach secrete histamine? a. Oxyntic c. D b. Chief d.
Enterochromaffin-like - ✔✔ANSW✔✔..D: Enterochromaffin-like
Of the available options, only enterochromaffin-like cells secrete histamine.
The presence of chyme in the duodenum stimulates which hormones? a. Motilin and
histamine b. Secretin and cholecystokinin c. Enteroglucagon and gastric inhibitory
peptide d. Somatostatin and acetylcholine - ✔✔ANSW✔✔..b: secretin and
cholecytokinin
The movement of chyme from the stomach into the duodenum initiates the intestinal
phase of secretion. This phase represents a slowdown of the gastric secretory
response; however, the presence of digested protein and amino acids in the duodenum
continue to stimulate some gastric secretion. The release of secretin and
cholecystokinin stimulate pancreatic secretions and inhibit gastric secretions. This
selection is the only option that correctly identifies the hormones that are stimulated by
the presence of chyme in the duodenum.
Which gastric hormone inhibits acid and pepsinogen secretion, as well as decrease the
release of gastrin? a. Bombesin c. Somatostatin b. Histamine d. Acetylcholine -
✔✔ANSW✔✔..ANS: C Of the options available, only somatostatin inhibits the secretion
of acid and pepsinogen and decreases gastrin release.
Which enzyme breaks down protein-forming polypeptides in the stomach? a.
Acetylcholine c. Gastrin b. Pepsin d. Secretin - ✔✔ANSW✔✔..ANS: B Of the options
available, only pepsin, a proteolytic enzyme, breaks down protein-forming polypeptides
in the stomach.
One of the many sequelae associated with cirrhosis is hepatic encephalopathy. It is a
cause by the inability of the liver to:
a) detoxify ammonia
b) synthesize glycogen
c) produce bile
