Définition
Sens technique
Natural diffusion of a solvent through a semi-permeable membrane from a dilute solution to a concentrated solution. The difference in concentration creates a pressure known as osmotic pressure, the effect of which is to equalise the concentrations on either side of the membrane, and consequently to dilute the more concentrated solution. Osmosis plays a key role in the circulation of water in living organisms.
