Electrolytes and Osmolytes Quiz 2

1- Their composition is very similar
intracellular and extracellular fluids
interstitial fluid and plasma
plasma and urine
1st and 2nd are correct


2- Usually higher levels outside cells than inside
Mg+2 and proteins
Cl- and Na+
ATP and GTP
all of the above


3- An osmolyte
is a charge ion
its concentration is measured in mOs
drives water movement due to its charge
1st and 2nd are correct


4- Addition of hypertonic fluid to the interstitial compartment will induce
water movement out of cells
ion movement out of cells
increased intracellular volume
decreased extracellular volume


5- Shortly after a volume of water fluid enters the interstitial compartment
volume of the interstitial compartment increases
volume of the intracellular compartment increases
added water volume equilibrates between the interstitial and intracellular compartments
volume of interstitial compartment decreases
