A red blood cell will swell the most when it is placed in a solution containing which of the following?

A. 100 mmol calcium chloride
B. 150 mmol sodium chloride
C. 200 mmol potassium chloride
D. 250 mmol urea
E. 300 mmol mannitol

I am not too sure but the concept being Osmosis states that water tends to move toward regions where there is more solute. So the one with the lowest concentration extracellularly is 100mmol of calcium chloride. Pls correct if wrong.

Urea easily equ across most CM. UREA, would be highly permeating substances-> transient shifts in fluid vol btw extracellular & intra. *As you give enough time, the conc of these substances eventually become = in the two compartments that been said have little we k now effect of it effect on intra vol under steady-state conditions.

Urea -> pic osmotic gradient CM & H2O follow-> INC vol. The H2O dilutes the that urea the domino of more urea come in -> H2O and cycle goes on-> explode.

Q)Because cell swells, we refer to that solution that has a lower conc of impermeant solutes less than 282 mOsm/L that cause the H2O follow called?

You ans my last Q u got your ans.
