Blood circulates throughout our body, through each cell and organ, to carry oxygen and nutrients, helping us to stay healthy. Blood pressure determines the force with which the blood flows through our veins. However, many more factors come into play so that this entire process is carried out perfectly.
If our blood is liquid and if the capillaries of our skin can absorb substances from the outside, how is it that the blood does not leak out of the capillaries? Well, thanks to colloid osmotic or oncotic pressure. This article explains the definition of colloid osmotic pressure and why it is so essential for our well-being.

What is the colloid osmotic pressure concept?
Also known as oncotic pressure, the pressure exerted by plasma proteins that cause the liquid to remain within the capillaries. When several large particles are concentrated in a solution, as is the case of protein molecules that are present in our blood, this concentration exerts a pressure that does not allow them to pass through the capillary membrane, causing the blood cannot to leak out of our capillaries.
Although the layer that lines our capillaries is skinny, which makes them very absorbent, the proteins present in our blood plasma can extract water, helping it to remain in the capillaries. In our body, we have different types of proteins. However, about 70% of the colloid osmotic pressure exerted is the responsibility of albumins, the most abundant type of protein in our blood.
The oncotic pressure may be higher depending on the area of the body. For example, in those capillaries with a higher filtration, such as the kidneys, the pressure concentration will be higher to work more effectively.
The risks of not having enough protein
Eating a balanced diet that allows us to receive a good amount of proteins through the diet is essential because when their levels are reduced in the blood, the colloid osmotic pressure can be affected and, therefore, conditions such as edema may occur. The excessive presence of fluid in any organ or tissue of the body can put our health at risk.
Because there is less protein in our bloodstream to contain fluid, it can accumulate in specific tissues, causing retention and complications.
