Plasma contains not only blood but also in tissues of the body. The substance contains several hundreds of vital elements. For example, it is possible to detect the bilirubin, salt, vitamins C, D, insulin, urea, estrogen and uric acid. Plasma dilutes the blood and gives it the best consistency for the transportation of vital substances to all cells in the human body. It also contains fibrinogen, which plays the most important role in blood clotting.
93% of the total mass of plasma is water, and the rest – proteins, lipids, minerals and carbohydrates. When extracted from blood fibrinogen, it is possible to obtain the serum containing the required antibody, widely used in medicine for healing serious diseases.
Plasma with a high content of platelets is widely used in medicine for tissue healing in the body.
Blood plasma is taken as an important item for donation. During sampling it is collected in a sterile package, and then by running the centrifuge is separated into red blood cells, which after the operation are returned to the donor.
Functions of the plasma
Plasma protein performs several important functions. The most important of these is nourishing the blood cells capture proteins and split them with the help of special enzymes to help with digestion.
Proteins of the globulin contained in the blood, provide protective, transport and pathological functions of the body.
Transport function of plasma is to carry nutrient molecules to the site of the body where certain cells are consumed. It provides colloid osmotic pressure that regulates the water balance between the cells. Osmotic pressure is implemented through a portable plasma minerals. The buffer function is implemented to help maintain the proper acidic balance in the body, and proteins prevent the appearance of bleeding.
Plasma also contains cytokine – substances that are responsible for inflammation and answers immune response of the body to stimuli. The number tsitokinov used in the diagnosis of sepsis or rejection of donor organs. Exceeded the concentration of uric acid in the blood may indicate gout or a decline in renal function, which is observed in hepatitis and certain medications.
