Question
1.If the aquaporins in the descending Loop of Henle were mutated and could not transport water the kidney would?
a) Not reabsorb sodium in the Loop of Henle
b) Not efficiently reabsorb water in the collecting duct
c) Still reabsorb sodium in the descending Loop of Henle
d) None of the above
18. Glucose
a) Is co-transported with sodium by secondary active transport
b) Reabsorption requires the Na+/K+ ATPase pump
c) 100% reabsorption occurs when blood glucose levels exceed 300 mg/dl
d) a and b are correct
30. Glomerular filtration rate is?
a) Maintained constant by myogenic autoregulation which dilates the afferent arteriole when blood pressure increases
b) Maintained constant by myogenic autoregulation which constricts the afferent arteriole when blood pressure decreases
c) Maintained constant by myogenic autoregulation which constricts the afferent arteriole when blood pressure increases
d) Maintained constant by juxtaglomerular feedback which responds to flow past the proximal tubule
37. What can follicle stimulation hormone (FSH) secretion be inhibited by

c) Progesterone
d) a) and b)
e) All the above
23. During the proliferative phase:
a) Estrogen decreases the growth of spiral arteries
b) Estrogen causes cervical mucus to thicken and become sticky
c) Estrogen and FSH induce formation of more FSH receptors on granulosa cells
d) Estrogen causes an increase in body temperature
9. Glucose
a) Is co-transported with sodium by secondary active transport
b) Reabsorption requires the Na+/K+ ATPase pump
c) 100% reabsorption occurs when blood glucose levels exceed 300 mg/dl
d) a and b are correct
Explanation / Answer
1. Aquaporins in the descending loop of Henle:
(b) Not efficiently reabsorb water in the collecting duct.
The reabsorption in the Loop of Henle is impaired. Sodium reabsorption would not be affected because it takes place in the ascending loop.
18. Glucose:
(d) a and b are correct.
It is co transported with sodium by secondary active transport and transportion requires the Na+/K+ ATPase pump.
30. Glomerular filtration rate is:
(b) maintained constant by myogenic autoregulation which constricts the afferent arteriole when blood pressure decreases.
37. Follicle stimulating hormone ( FSH) is a gonadotropin a glycoprotein polypeptide hormone. It is inhibited by estrogen.
(a) Estrogen
23. Proliferate phase:
(c) Estrogen and FSH induce information of more FSH receptors on granulosa cells.
9. Glucose:
(d) a and b are correct
It is co transported with sodium by secondary active transport and transportion requires the Na+/K+ ATPase pump.
