BIO 322 Test 3 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. Correct Answers 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.
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? Correct Answers submucosa
A transfusion of serum would differ from a transfusion of saline
in that 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 Correct Answers increases water
permeability of the distal convoluted tubule and the collecting
duct, and increase water reabsorption.
Auroregulation of GFR Correct Answers maintains an
adequate GFR despite changes in local blood pressure.
Blood movement into capillaries around an alveoli Correct
Answers is perfusion
, Calculate the osmotic concentration of a solution containing 100
mM NaCl and 50 mM glucose. 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.
Correct Answers mucosa- submucosa- muscularis externa -
serosa
Decreasing GFR Correct Answers stimulates renin release by
the juxtaglomerular complex which triggers the formation of
angiotensin 1
During dehydration Correct Answers plasma protein
concentration increases which will increase glomerular capillary
reabsorption leading to lower GFR.
During lab you calculated the amount of filtrate reabsorbed per
day. I think that if you did it , or if you checked the key, you will
remember it because it's amazing. What does your memory tell
you (or your knowledge)? Correct Answers 180 L of filtrate
per day
Glomerulonephritus Correct Answers is an inflammation of the
glomeruli that impairs filtration in the kidneys.
How does the renin- angiotensin aldosterone system work?
Correct Answers Reduced blood flow to the kidneys triggers
renin secretion, which activates a cascade of reactions that
