os·mo·sis O0138500 (ŏz-mō′sĭs, ŏs-)n. pl. os·mo·ses (-sēz) 1. a. Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal solute concentration on both sides of the membrane.b. The tendency of fluids to diffuse in such a manner.2. A gradual, often unconscious process of assimilation or absorption: learned French by osmosis while residing in Paris for 15 years.
[From obsolete osmose, from earlier endosmose, from French : Greek endo-, endo- + Greek ōsmos, thrust, push (from ōthein, to push).]

Synonym(s): osmolar. osmosis (oz-mō′sĭs) [Gr. osmos, impulse, + osis, condition]  OSMOSISThe 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.
