Re: Urea and membrane permeability of RBC

... of the membrane is the same (facilitated diffusion). But now the osmolarity of the intracellular solution is higher than the osmolarity of the extracellular solution. Water will go and find the osmoles. Water will cross into the cell until the osmolarity is the same inside and outside the cell. ...
