value of the blood can not be overestimated.This fluid is completely provides the livelihoods of organs and tissues and removes waste products of metabolism.It is through the blood of every cell in the body is able to fully exist.
Blood consists of more than half of the plasma.Plasma - is a liquid which comprises a slurry of blood elements - they comprise about ten percent of the plasma.The composition of the plasma is extremely diverse - this amino acids and peptides, bilirubin, creatine, and many other inclusions.Furthermore, in the blood plasma proteins are included - one of the most important elements.
Depending on the structure of its proteins are also divided into groups - is albumin, fibrinogen, globulins and prothrombin.All of them are included in the plasma, while fulfilling various functions.Blood plasma, the functions of which are very numerous, it is recommended for transfusion in case of surgery.In many respects the plasma can help a person in need of transfusions.
most numerous among all the protein albumin.They are very easy (the smallest molecular mass of all the elements), so it is easy to transport and connect with other elements.Albumin in the liver.The second largest category of proteins - globulins, which are also produced by the liver.Much less in plasma fibrinogen found - it is only about four percent, but nevertheless very important for many protective processes.And quite a bit of blood contains prothrombin.
proteins that make up blood plasma, perform different functions.Due to the distribution of water which is between the tissues and blood vessels, is preserved consistency of the liquid medium, the cells are provided with nutrients and "clean" from the metabolic products, waste and no need for the body.In addition, proteins are actively involved in the protective functions.
Albumin maintain the osmotic pressure of blood.This means that they are responsible for correct blood pressure at each point of the liquid body.If part of the albumin in the blood falls, it could lead to the removal of fluid and edema formation (a vivid example of lowering the level of albumin - the second half of pregnancy, preeclampsia).Another important function of albumin - transport of various substances.Albumin is transferred as a beneficial nutrients and toxins are neutralized by the body by the liver.
Globulins largely responsible for the body's immunity, agglutination (the ability of red blood cells to stick together, so that the blood is determined).
Prothrombin together with fibrinogen gives us a measure of blood viscosity, which is especially important, because the greatest mortality in the post-Soviet countries is cardiovascular disease.Composition plasma largely affects the ability of blood vessels and the heart to the optimum transfer of blood through the body.It prothrombin and adjusts the viscosity, and thus affects the ability of blood vessels to the easy to carry blood throughout the body.
Fibrinogen - an active participant in the process of coagulation.It is due to fibrinogen formed a fibrin strands, which form a thrombus - clot.When it opens, bleeding effect of fibrinogen helps stop blood clots and crusts (if the wound on the surface of the hole).This ability of blood to save the body from clotting significant blood loss.However, some people suffer from a disease like hemophilia - the inability of blood clots.If the X chromosome carries failure information, it can lead to a lack of deposition of fibrin strands and, hence, the impossibility of formation of a blood clot.This defect once again illustrates how important is the function of fibrinogen, as hemophiliacs are under constant fear of death from blood loss at the slightest damage.
composition of blood plasma varied, but that proteins play a most important function.For a man it is important to have regular tests to determine the amount of protein elements and, if necessary, take action to establish homeostasis in the blood environment.
