That part of plasma osmotic pressure exerted by proteins.
The pressure exerted by the plasma proteins on the walls of the vascular system. These proteins are too large to pass through the capillaries, hence this pressure is noted only in the large vessels.
Pressure within a blood vessel exerted by the presence of colloid molecules, such as proteins; this pressure tends to help retain fluid within the walls of the blood vessels, especially the capillaries. Loss of protein (colloid), such as in kidney failure, may allow the pressure to decrease. The vessels then leak, resulting in tissue fluid and swelling (edema).
A pressure represented by the pressure difference that exists between the osmotic pressure of blood and that of the lymph or tissue fluid. Oncotic pressure is important for regulating the flow of water between blood and tissue fluid.
Osmotic pressure exerted by colloids in a solution.
Oncotic pressure, also referred to as colloid osmotic pressure, is a type of osmotic pressure exerted by proteins, typically albumin, in the plasma of blood. This pressure acts to attract fluid into the circulatory system.
The osmotic pressure created by colloids in a solution, which fluctuates due to changes in the colloidal molecule composition.
