(oz-mō′sĭs) [Gr. osmos, impulse, + osis, condition]
Enlarge picture
The passage of solvent through a semipermeable membrane that separates solutions of different concentrations. The solvent, usually water, passes through the membrane from the region of lower concentration of solute to that of a higher concentration of solute, thus tending to equalize the concentrations of the two solutions. The rate of osmosis is dependent primarily upon the difference in osmotic pressures of the solutions on the two sides of a membrane, the permeability of the membrane, and the electric potential across the membrane and the charge upon the walls of the pores in it. See: illustration

reverse osmosis

A form of water treatment that removes infectious particles and dissolved ions more effectively than other water purification techniques. Water so purified can be used in hemodialysis.

concentration of osmotically active particles in solutions.
osmotic fragility
the susceptibility of red blood cells to hemolyze in hypotonic saline solutions; may be used as a test of red cell fragility when a series of increasing concentrations is used. See also erythrocyte fragility.
