MSH: The pressure required to prevent the passage of solvent through a semipermeable membrane that separates a pure solvent from a solution of the solvent and solute or that separates different concentrations of a solution. It is proportional to the osmolality of the solution.,CSP: pressure generated by the mass flow of water to that side of a membrane bounded structure that contains the higher concentration of solute molecules.
