Troubleshooting
• If you weren’t able to begin the game, it’s probably
because your PowerPoint security settings are set too
high. Here’s what to do:
– Open PowerPoint and choose ‘Options’ from the ‘Tools’ menu
– Click on the ‘Security’ tab and on ‘Macro Security’ in the lower
half of the screen.
– Set Macro security at ‘Medium’ and close PowerPoint.
• Click the button below to go back to the Main Menu, and
re-open this quiz. The computer should ask you whether
you want to enable macros. Tell it to enable them.

The three stages of digestion, in
correct order, are:
Cephalic
Intestinal
Gastric

Which part of the autonomic
nervous system is activated during
digestion?
Peripheral
Sympathetic
Parasympathetic
Unsympathetic
Central
Mucosal
During digestion, smooth muscle
activity in the gut:
Stops
Increases and
then decreases
Increases
Decreases and
then increase
Decreases
Does not change
Carbohydrates are digested by the
enzyme:
Amylin
Lipase
Pepsin
Amylase
Carboxypeptidase
Glucagon
Carbohydrate molecules are
broken down into:
Saccharin
Glycerol
Polysaccharides
Glycogen
Polypeptides
Monosaccharides and
disaccharides
When they have been absorbed
into the blood, monosaccharides:
Are picked up by cells
using
glucose porter proteins
Leave the body
in the stools
Are released
into the urine
Are destroyed
by the liver
Leave the body
in the sweat
Stimulate
glucagon secretion
To make the glucose porter
proteins, cells need:
Glucagon
Insulin
Pepsin
Amylase
Amylin
Glycogen
Without insulin, the digested
sugars:
Accumulate in the blood
Enter fat cells
Pass out in the stools
Go out in the sweat
Are made into proteins
Are converted back
into carbohydrates
If Insulin is present, excess sugar
is:
Picked up by cells
and stored as starch
Released in the urine
Picked up by the cells
and stored as glucagon
Released into the stools
picked up by the cells
and stored as glycogen
Returned to
the intestinal contents
When the blood glucose is low, the
pancreas secretes:
Insulin
Glucagon
Glycogen
Amylin
Amylase
Secretin
Glucagon causes the cells to:
Secrete
digestive enzymes
Break down
their stored food and
release it to the blood
Build muscle
Pick up food
from the blood
Stop all metabolic activity
Make more glycogen
During the gastric phase, the
stomach:
Secretes trypsin and
pancreatic amylase
Inhibits intestinal motility
Turns off the
parasympathetic
nervous system
Opens the
pyloric sphincter
secretes HCl, mucus,
pepsinogen,
intrinsic factor, and gastrin
Closes the lower
esophageal sphincter
What is Gastrin?
A ligament holding the
stomach in position
A digestive enzyme that
sometimes causes ulcers
A soapy substance
lining the alveoli
A neurotransmitter
that tells your brain
your stomach is full
A substance in the sweat
that causes body odor
A hormone
that stimulates
stomach activity
What makes the stomach stop
creating Gastrin?
Decreased blood volume
Stretch receptors
in the stomach wall
Shrunken cells
The parasympathetic
nervous system
Hormones released
from fat cells
Hormones released
by the intestines
when food enters them
The pyloric sphincter lets food
through when:
The duodenum is empty
The stomach has
stopped secreting
digestive enzymes
The cephalic phase
of digestion begins
The stomach squeezes
small particles
down through it
Insulin is released
The parasympathetic
system turns on
The duodenum releases three
hormones. What are they?
Cortisol, aldosterone,
and testosterone
Secretin,
Cholecystokinin, and GIP
Antidiuretic hormone,
Parathyroid hormone, and
Growth hormone
Insulin, glucagon,
and amylin
Gastrin, secretin,
and ghrelin
Secretin,
cholecystokinin,
and glucagon
One effect of cholecystokinin is:
Decreases
intestinal motility
causes the
gall bladder to send
bile into the duodenum
Causes insulin secretion
Nothing
Increases blood K+
Causes hunger
What does the pancreas do in
response to cholecystokinin?
Releases insulin
Sends digestive enzymes
to the duodenum
Releases glucagon
Sends bicarbonate
to the duodenum
Releases thyroxine
Sends acid
to the duodenum
What is bile?
An antacid that protects
the duodenum
A hormone that
tells the brain
the man has eaten fats
A digestive enzyme that
breaks down fat molecules
A neurotransmitter
that turns
off stomach motility
A compound made from
bilirubin and cholesterol,
used to emulsify fats
A toxic compound caused
by white blood cell
breakdown
Where is bile made?
The liver
The stomach
The spleen
The gall bladder
The bone marrow
The thymus
A man with liver failure might
develop:
High blood osmolarity
Acne
Sunken eyes
Constipation
Low body temperature
Fatty stools
The food absorbed from your gut
contents goes straight to the:
Hepatic portal vein
Urine
Heart
Fat cells
Stools
Brain
