BIOL 2200 - Exam 4 Practice Questions With Correct
Answers
Which |of |the |following |animals |generally |has |the |lowest |volume |of |urine |production? |- |
CORRECT |ANSWER✔✔-marine |bony |fish
Birds, |insects, |and |many |reptiles |excrete |nitrogenous |wastes |in |the |form |of |uric |acid, |which |
__________. |- |CORRECT |ANSWER✔✔-reduces |water |loss |compared |to |other |nitrogenous |
wastes, |but |requires |more |metabolic |energy |to |produce
Because |uric |acid |is |not |very |soluble |in |water, |it |can |be |excreted |in |a |paste-like |form |with |very
|little |loss |of |water. |However, |its |synthesis |requires |the |hydrolysis |of |ATP.
The |movement |of |substances |out |of |the |glomerulus |and |into |Bowman's |capsule |is |referred |to |
as |_____. |- |CORRECT |ANSWER✔✔-filtration
Blood |pressure |is |the |force |behind |the |filtration |of |substances |out |of |the |glomerulus |and |into |
Bowman's |capsule.
The |movement |of |substances |from |the |blood |into |the |proximal |tubule |is |known |as |_____. |- |
CORRECT |ANSWER✔✔-secretion
Which |of |these |is |reabsorbed |from |filtrate?
A) |sodium |chloride
B) |glucose
C) |water
D) |amino |acids
E) |all |of |these |- |CORRECT |ANSWER✔✔-all |of |these
, All |of |these, |as |well |as |bicarbonate |ions, |are |reabsorbed |from |the |filtrate.
As |filtrate |moves |down |the |loop |of |Henle, |the |surrounding |interstitial |fluid |becomes |_____ |
concentrated |than |the |filtrate, |so |_____ |leaves |the |filtrate. |- |CORRECT |ANSWER✔✔-more |... |
water
The |increasing |solute |concentration |of |the |interstitial |fluid |results |in |water |leaving |the |filtrate |
by |osmosis.
The |most |abundant |solute |in |urine |is |_____. |- |CORRECT |ANSWER✔✔-urea |(and |other |
nitrogenous |wastes)
Nitrogenous |wastes, |such |as |urea, |are |the |primary |solute |found |in |urine.
Glucose |is |removed |from |filtrate |by |_____. |- |CORRECT |ANSWER✔✔-active |transport
Examine |the |figure |of |a |human |nephron. |Where |and |when |does |osmolarity |of |the |filtrate |
increase? |- |CORRECT |ANSWER✔✔-As |the |filtrate |moves |down |the |descending |limb |of |the |loop
|of |Henle
Review |how |the |human |kidney |concentrates |urine. |The |osmolarity |of |the |filtrate |increases |
from |300 |to |1,200 |mOsm/L |as |it |moves |down |the |descending |limb |of |the |loop |of |Henle.
Which |of |the |following |is |an |advantage |of |excreting |nitrogenous |wastes |as |urea |rather |than |as
|ammonia? |- |CORRECT |ANSWER✔✔-urea |is |less |toxic |than |ammonia
Researchers |at |a |pharmaceutical |company |are |working |to |develop |a |new |drug |that |would |
cause |a |patient |to |produce |urine |that |is |less |concentrated. |Which |of |the |following |drugs |
