1.      Renal corpuscle
2.      Collecting duct
3.      Loop of Henle
4.      Distal tubule
5.      Proximal tubule

Arrange the parts in order as fluid flows from the filtration membrane through the nephron.
a)      1,5,3,4,2
b)     2,4,1,3,5
c)      2,1,4,5,3
d)     4,2,3,5,1
e)      5,1,3,4,2

2.      Active transport of substances from the blood into the nephron is called
a)      Filtration
b)     Excretion
c)      Secretion
d)     Reabsorption
e)      Absorption

3.      The movement of substances from the filtrate back into the blood of the peritubular capillaries is called
a)      Filtration
b)     Secretion
c)      Excretion
d)     Reabsorption
e)      Absorption

4.      Which of these substances normally cannot pass through the filtration membrane?
a)      Hemoglobin
b)     Glucose
c)      Sodium
d)     Water

5.      Which of these conditions increases the amount of urine produced?
a)      ADH
b)     ANP
