Dictionary » E » Extracellular




Occurring or being (situated) outside the cell or cells.

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. ...

Speed of Osmosis

From my understanding, osmosis occurs to balance out the concentration of water molecules between the intracellular and extracellular environment. So if in the inside of the cell, the salt concentration is increasing, the outside of the cell therefore has an increased concentration ...
