Thus, fluid generally moves out of the capillary and into the interstitial fluid. This process is called filtration. Osmotic Pressure. The net pressure that drives reabsorptionâthe movement of fluid from the interstitial fluid back into the capillariesâis called osmotic pressure (sometimes referred to as oncotic pressure).
Movement of oxygen into the blood. Diffusion of oxygen into the blood takes place at the alveoli (air sacs). The air in the alveoli contains a lot of oxygen. The alveoli are very close to capillaries, which are small blood vessels. The blood in the capillaries has very little oxygen and has a lot of carbon dioxide. The walls of both the alveoli and the capillaries are very thin and oxygen and carbon dioxide molecules can move through these walls.
