Plasma is considered the fourth state of matter, according to Physics. This is obtained from the overheating of gases, causing their molecules to break, producing ions and electrons that are neutral to each other.
Even though it is not so common on Earth, plasma is present in abundance throughout the Universe, and it can be observed densely mainly in stars such as the Sun and other materials. intergalactics.
Another particularity of the plasma is its great sensitivity to electromagnetic fields, so that its shape can be molded according to the influence of magnetism.
In everyday life, the use of plasma is common at microscopic scales for the development of some technologies, such as plasma lamps and the plasma televisions, for example.
Blood plasma
consists of a yellowish liquid that makes up approximately 55% of the blood, along with red blood cells (erythrocytes), white blood cells (leukocytes) and platelets.
The main function of blood plasma, because it is liquid, is to facilitate the transport of all substances present in the blood to the body.
Other essential functions for the functioning of the organism and which are performed by the blood plasma are: transport of carbon dioxide, which is taken to the lungs where it is released on expiration; transport of nutrients to all cells in the body; it helps in the body's defense and blood clotting.
Plasma and Serum
As stated, plasma is the liquid part of the blood, composed of several substances, including clotting elements (fibrinogen).
Serum is obtained from plasma, when the clotting elements are removed from it. That is, when the plasma does not have fibrogen, it becomes serum.
