HIGH – TECH NR 228 PRACTICE QUIZ
EXAM 2025 RATED A+
A substance that works only on a specific class of nutrients is called:
a) bolus
b) chyme
c) gastrin
d) enzymes
d) enzymes
NOTE: Enzymes work on specific classes of nutrients to change them
from one form to a simpler form. A bolus is a ball-shaped mass of
chewed food that is swallowed. Chyme is the semiliquid mixture of
food mass and secretions in the stomach. Gastrin is a hormone
secreted by the stomach mucosa.
A bolus is a ball of:
a) masticated food ready to be swallowed
b) fat emulsified with bile and intestinal secretions
c) mucus that helps move food along the GI tract
,d) indigestible fiber mixed with the waste products of digestion
a) masticated food ready to be swallowed
The villi of the small intestine increase its capacity for:
a) digestion
b) absorption
c) excretion
d) elimination
b) absorption
NOTE: Villi increase the surface area of the small intestine which makes
it possible for it to absorb more nutrients. Digestion occurs in the small
intestine, but is not a function of the villi. Excretion and elimination do
not occur in the small intestine.
If the large intestine did not carry out its main function, feces would be:
a) alkaline
b) acidic
c) liquid
d) very dry
c) liquid
,NOTE: A major function of the large intestine is absorption of water, so
feces would be liquid. Feces would not be dry if they large intestine was
not removing water. The large intestine does not have a significant
impact on the acidity or alkalinity of feces.
The esophagus is a structure that:
a) produces & releases digestive enzymes but not hormones
b) does not produce digestive enzymes but does release hormones
c) does not produces or release digestive enzymes or hormones
d) produce only small amount of digestive enzymes or hormones
c) does not produces or release digestive enzymes or hormones
NOTE: The esophagus does not produce or release digestive enzymes or
hormones. It simply transports food boluses from the mouth to the
stomach.
The esophagus is the:
a) muscular tube use for excretion of waste products.
b) pathway through which enzymes & hormones travel.
, c) pathway that blood follows within the body from organ to organ.
d) muscular tube along which a food bolus travels from the mouth to
the stomach.
d) muscular tube along which a food bolus travels from the mouth to
the stomach.
Plants use carbon dioxide, water & the sun's energy in the process of
photosynthesis to synthesize:
a) fat
b) protein
c) carbohydrates
d) alcohol
c) carbohydrates
NOTE: Plants synthesize carbohydrate via photosynthesis. Fat and
protein are produced by other metabolic processes in the plants. Living
plants do not usually produce alcohol, although stored fruit or grain
may ferment and produce some alcohol.
29. Compared with table sugar (sucrose), honey tastes_____ because it
contains _____:
