[Plasma osmotic pressure and oncotic pressure].
Water distribution in the body fluid is controlled by osmotic pressure and oncotic pressure of plasma. Lower plasma osmotic pressure induces intracellular edema, while lower plasma oncotic pressure induces extracellular edema. The increase in osmo-active substance in plasma induces increase in plasma volume (or extracellular fluid), and then results in extracellular edema.
