AND CORRECT ANSWERS
Question:
1. Which major process involves the movement of digested
end products from the lumen of the GI tract into the
blood or lymph, by passing mainly through the mucosal
cells of the small intestine?
a) defecation
b) ingestion
c) absorption
d) mechanical breakdown
Answer:
c) absorption
Question:
2. Which organ is the major site for
digestion?
a) liver
b) stomach
c) large intestine
d) small intestine
Answer:
d) small intestine
Question:
3. Which of the following functions is NOT correctly
matched with its
description?
a) propulsion: physical breakdown of ingested food in
the GI tract
b) absorption: transport of chemically digested nutrients
into the blood or lymph
c) ingestion: taking food into the digestive tract
d) mechanical breakdown: churning movements in the GI
tract
Answer:
a) propulsion: physical breakdown of ingested food in the GI tract
,Question:
4. When we ingest large molecules such as lipids,
carbohydrates, and proteins, they must undergo
catabolic reactions whereby enzymes split these
molecules. This series of reactions is called
________.
a) secretion
b) chemical digestion
c) absorption
d) mechanical breakdown
Answer:
b) chemical digestion
Question:
5. Digestion reduces large complex molecules to simpler
compounds by the process of
________.
a) anabolism
b) catabolism
c) mastication
d) excretion
Answer:
b) catabolism
Question:
6. All the chemical and mechanical phases of digestion
from the mouth through the small intestine are directed
toward changing food into forms that can pass through
the epithelial cells lining the mucosa into the underlying
blood and lymphatic
vessels.
True
False
Answer:
true
, Question:
7. Which layer of the alimentary canal contains either
stratified squamous or simple columnar
epithelium?
a) serosa
b) mucosa
c) submucosa
d) muscularis externa
Answer:
b) mucosa
The mucosa's inner lining is composed of simple columnar epithelium in most of
the alimentary canal. Stratified squamous epithelium is found in the esophagus,
oral cavity, and anus.
Question:
8. Which layer of the digestive tract contains the effectors
for digestive
propulsion?
a) submucosa
b) mucosa
c) muscularis externa
d) serosa
Answer:
c) muscularis externa
The smooth muscles in the muscularis work to make the propulsive movements
called
peristalsis
Question:
9. Peritoneal organs are completely covered in a serous
membrane and have a dorsal and ventral mesentery.
True
False
Answer:
False
Peritoneal organs are covered in a serous membrane, the peritoneum. However,
many peritoneal organs only have a dorsal mesentery. A ventral mesentery is only
evident on a few peritoneal organs.
