6
Q
hypotonic fluid affects on body
A
shifts fluid out of the intravascular compartment, hydrating the cells and the interstitial compartments (into intracellular space)
~water moves into cells, possibly causing them to burst
7
Q
hypertonic fluid affect on body

draws fluid into the intravascular compartment from the cells & the interstitial compartments
