    It means the diffusion of fluids through a membrane. Oxygen is diffused into your blood through the alveoli walls by osmosis. The difference between diffusion generally and osmosis is the permeable membrane. osmosis is a type of diffusion. diffusion is when particles spread out from an area of high concentration to evenly disperse themselves in a container that they're in. for example: if you go to a concert or something they usually use fog machines. when they first turn it on, the fog is only in a small area. if you notice 5 minutes later, the fog will be spread out in the air of the entire building. osmosis is the same thing except more specific: it is the movement of WATER molecules across a CELL's MEMBRANE. (water moving from an area with lots of water to an area with less water)

    Osmosis is the net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration, in order to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves, without input of energy, across a semi permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations. Although osmosis does not require input of energy, it does use kinetic energy and can be made to do work.
