Trang 5ANS: D
In the mouth, salivary glands secrete salivary amylase, which is the general name for any starch-splitting enzyme Thus a food with starch content, such as bread, could begin its chemical digestion in the mouth
6 After ingested food is mixed and churned with gastric secretions, the
semifluid mass is called
By the time the food mass reaches the lower portion of the stomach, it is a
semiliquid, acid-food mix called chyme

The intestinal muscles produce several types of movement that aid digestion,
including peristalsis, pendular movements, segmentation, longitudinal rotation, and surface villi motions

Trang 1113 A meal consisting of country fried steak, carrots, and a baked potato with butter and sour cream would stimulate the hormone cholecystokinin because
of the
a presence of food in the duodenum
b presence of fat in the duodenum
c entry of the acidic chyme into the duodenum
d entry of bile into the duodenum
ANS: B
The stimulus for the release of cholecystokinin is the presence of fat in the
duodenum Once stimulated, cholecystokinin stimulates the gallbladder to release bile to emulsify fat
14 After eating fried chicken the end products from the digestion of fat include
a glycerol and fatty acids
Trang 12b glucose and fatty acids
c amino acids and dipeptides
d cholesterol and glycerol
Trang 14c excretion of waste products
d completion of the digestive process

18 Bacteria found in the colon are significant because they
a synthesize some vitamins
b are a source of contamination
c finish digesting whatever remains in the colon
d are necessary for mineral absorption
19 Gas formation in the colon is the result of
a ingestion of certain foods
Trang 16b ingestion of too much water
c inadequate ingestion of fiber
d bacterial action on undigested items
Trang 17c adds bulk to feces
d absorbs excess nutrients
ANS: C
Trang 18Food fiber is not digested because human beings lack the specific enzymes required, but adds bulk to the diet
22 The sum total of all the chemical changes that an organism performs to
maintain its life and produce energy is the result of
Trang 1924 Two organs that work with the small intestine in digestion are the
a liver and kidneys
b stomach and large intestine

d large intestine and colon

d increase the number of enzyme-secreting cells
