Water diffusivity: comparison of primary CNS lymphoma and astrocytic tumor infiltrating the corpus callosum. Osmosis is when water moves from an area of LOW solute concentration (low osmolarity) to an area of HIGH solute concentration (high osmolarity) through a semipermeable membrane. Since the solute particles are incapable of crossing the membrane, its the water (or other solvent) that needs to move. The flow of water will be prevented when both the pressure (inside and outside) are equal.
