WebFeb 6, 2024 · How does albumin maintain osmotic pressure? Albumin in plasma is the body’s natural colloid. The osmotic pressure created by colloids creates a “pull” to fluid … WebColloid osmotic pressure (COP), the osmotic pressure exerted by large molecules, serves to hold water within the vascular space. It is normally created by plasma proteins, namely albumin, that do not diffuse readily across the capillary membrane. Inadequate COP can contribute to vascular volume loss and peripheral edema.
