BIO 322 Test 3 Pre Test Questions With Complete Solutions
1 Jolly Rancher candy has 11 grams of sugar. What is a
reasonable value for blood sugar after eating just 1 candy?
Assume that insulin is not secreted and that all of the sugar is
absorbed into the blood.
11 grams into 5 L = 2.2 grams/L. Converting to mg/dl gives 220
mg/dl. Adding this to a person's blood would increase blood
sugar to around 300 mg/dL.
11 grams into 10 L = 1.12 mols/L. Converting to mg/dl gives
110 mmols/dl. Adding this to a person's blood is no big deal.
would increase blood sugar to around 300 mols/dL.
11 grams into 5 L = 2.2 grams/L. Converting to mg/dl gives 220
mg/dl. Adding this to a person's blood would increase blood
sugar to around 300 mg/dL.
1 hard candy DOES NOT change blood sugar levels
significantly. That's just common sense. Correct Answers 11

A baby is brought to the hospital because he has projectile
vomiting. The diagnosis is hypertrophic pyloric stenosis. The
treatment is to carefully cut the layer of circular muscle to
enable the stomach contents to pass to the duodenum more
easily. What deep layer of tissue will the surgeon be careful to
avoid cutting?
Submucosa
Circular muscle
,Muscularis externa
Myenteric plexus Correct Answers submucosa
A transfusion of serum would differ from a transfusion of saline
in that
The number of red blood cells in the blood would decrease less
with serum compared to saline.
The hematocrit would increase after serum transfusion because
formed elements are a part of serum but are not included in
saline.
Blood clotting is enhanced with serum because it contains
fibrinogen.
The plasma protein concentration of the blood would not change
after serum transfusion, because serum has many proteins and
saline does not. Correct Answers The hematocrit would
increase after serum transfusion because formed elements are a
part of serum but are not included in saline.
Antidiuretic hormone
increases water permeability of the distal convoluted tubule and
the collecting duct, and increase urine flow.
a diuretic conserves water, so an anti diuretic will do the
opposite, and increase water elimination.
increases water permeability of the distal convoluted tubule and
the collecting duct, and increase water reabsorption.
increases water permeability of the entire nephron resutlign is a
vey dilute urine,. Correct Answers increases water permeability
of the distal convoluted tubule and the collecting duct, and
increase water reabsorption.
, Auroregulation of GFR
maintains an adequate GFR despite changes in local blood
pressure.
is a feedback mechanisms that influences total blood pressure
such that renal blood flow is maintained.
involves release of a paracrine substance form the
juxtaglomerular apparatus that has not been discovered yet.
involves release of renin when renal blood flow increases.
Correct Answers maintains an adequate GFR despite changes in
local blood pressure.
Blood movement into capillaries around an alveoli
is controlled by the respiratory centers within the CNS.
is perfusion.
Is determined by filtration rates.
is ventilation. Correct Answers is perfusion
Calculate the osmotic concentration of a solution containing 100

A. 250 mOsm/L
B. 300 Osm/L
C. 200 Osm/L
D. 400 mOsm/L Correct Answers A. 250 mOsm/L
Consider the microanatomy of the stomach, specifically, choose
the answer with the correct order for the layers of the stomach
wall when moving from the lumen to the interstitial fluid.
