Physiology, Colloid Osmotic Pressure Article - StatPearls

Oncotic pressure, or colloid osmotic-pressure, is a form of osmotic pressure induced by the proteins, notably albumin, in a blood vessel's plasma (blood/liquid) that causes a pull on fluid back into the capillary. Participating colloids displace water molecules, thus creating a relative water molecule deficit with water … See more 'Oncotic' by definition is termed as 'pertaining to swelling', indicating the effect of oncotic imbalance on the swelling of tissues. The word itself is derived from onco- and -ic; 'onco-' meaning … See more Throughout the body, dissolved compounds have an osmotic pressure. Because large plasma proteins cannot easily cross through the capillary walls, their effect on the … See more • Overview at cvphysiology.com See more In tissues, physiological disruption can arise with decreased oncotic pressure, which can be determined using blood tests for protein concentration.

WebAug 13, 2024 · It is referred to as colloid osmotic pressure (or sometimes as the oncotic pressure ). In plasma, the oncotic pressure is only about 0.5% of the total osmotic pressure. This may be a small percent but because colloids cannot cross the capillary membrane easily, oncotic pressure is extremely important in transcapillary fluid dynamics.
