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).

They are small enough that the oxygen can diffuse across the capillary wall into the tissue, and the carbon dioxide can diffuse from the tissue back into the blood. Capillaries are the structure where this gas exchange takes place.
