Plasma colloid osmotic pressure

In our lives, we should learn more about some health knowledge about our own bodies, because this can help us understand our physical health condition. Plasma colloid osmotic pressure is also a test method that can help people understand their own physical condition. Plasma colloid is very important for blood. Colloid can remove bacteria in the blood and effectively resist viruses.

Sometimes during a physical examination, the plasma colloidal osmotic pressure also needs to be tested, as it is also very important for the detection of some diseases. We can learn more about this knowledge so that we can better understand our own physical condition.

Plasma colloid osmotic pressure

The normal value of plasma colloid osmotic pressure is about 1.5mOsm/L (25mmHg or 3.3kPa). It is mainly composed of plasma proteins, among which albumin has a high content and a relatively small molecular weight, and is the main component of plasma colloidal osmotic pressure. Plasma colloidal osmotic pressure plays an important role in regulating the exchange of water inside and outside blood vessels and maintaining blood volume.

Knowledge

The plasma osmotic pressure is approximately 313mOsm/kgH2O, which is equivalent to 7 atmospheres 708.9kPa (5330mmHg). The osmotic pressure of plasma mainly comes from the crystal substances dissolved in it, especially electrolytes, which is called crystal osmotic pressure. Since the concentrations of crystal substances in plasma and tissue fluid are almost equal, their crystal osmotic pressures are also basically equal. Although plasma contains a large amount of protein, the molecular weight of the protein is large, and the osmotic pressure generated is very small, not exceeding 1.5mOsm/kgH2O, which is approximately equivalent to 3.3kPa (25mmHg), which is called colloid osmotic pressure. Since there is very little protein in tissue fluid, the colloid osmotic pressure of plasma is higher than that of tissue fluid. Among plasma proteins, the molecular weight of albumin is much smaller than that of globulin, and its molecular number is much greater than that of globulin, so the plasma colloid osmotic pressure mainly comes from albumin. If albumin is significantly reduced, the plasma colloid osmotic pressure will be significantly reduced even if globulin increases and the total plasma protein content remains basically unchanged.

Plasma proteins generally cannot pass through the capillary walls, so although the plasma colloidal osmotic pressure is small, it plays an important role in the water balance inside and outside the blood vessels. Since most of the crystal substances in plasma and tissue fluid cannot easily pass through the cell membrane, the relative stability of the crystal osmotic pressure of the extracellular fluid is extremely important for maintaining the water balance inside and outside the cells.

The above is an introduction to the information about plasma colloid osmotic pressure. I hope you can remember it after reading it, because such knowledge will be more or less useful to us. As long as we know more about the negative side, it is actually a kind of protection for ourselves and makes our body healthier.
