T/F: The nephron is the basic structural and functional unit of the kidney.
a)
True
b)
False
2.
How does the glomerulus filter blood into the Bowman's capsule?
a)
High pressure
b)
Concentration Gradient
c)
Active transport
d)
Passive transport
3.
Which portion of the nephron active pumps out Na+, with Cl- passively following, to create a salty medulla?
a)
Proximal convoluted tubule
b)
Ascending loop of Henle
c)
Distal convoluted tubule
d)
Both proximal convoluted tubule and ascending loop of Henle
4.
In the collecting duct, what is reabsorbed?
a)
Ions like Na+ and Cl-
b)
Nutrients like glucose and amino acids
c)
Substances like drug metabolites and waste
d)
Water
5.
Which statement best explains the flow of materials out of the nephron?
a)
The active transport of Na+ (and thus Cl-) creates salt, which pulls water using a concentration gradient in an attempt to create equilibrium
b)
The high pressure from the renal artery creates a force that pushes water through permeable areas, which creates an equilibrium in pressure
c)
There is no explanation. The kidneys work randomly and it is amazing that they function correctly.
d)
Water is actively transported out of the nephron and the nephron compensates by actively pushing out ions in an attempt to balance the charges
