White blood cells are also called leukocytes (English: white blood cell, WBC, leukocyte) and circulating in the human body is the circulatory system of cells that make up blood components.
Benefits of White Blood Cells
|Benefits of White Blood Cells|
In normal circumstances contained 4×10 to 11×10 9 9 white blood cells in a liter of blood in healthy adult humans – around 7000-25000 cells per drop.
In all there are 6000 millimeters of blood swelled to 10,000 (8000 average) of white blood cells. In the case of leukemia, the amount can be increased up to 50000 cells per drop.
In the body, leukocytes associate not tight with a particular organ or tissue, they work independently as a single cell organism.
Leukocytes are able to move freely and interact and capture cellular debris, foreign particles or microorganisms intruders.
In addition, leukocytes can not divide or be reproducing in their own way, but they are the product of pluripotent hematopoietic stem cells that exist in the bone marrow.
Leukocyte count less than that of erythrocytes. In men and women every cubic mm of blood there are only about 4,500 to 10,000 the number of grains.
Leukocytes have varied shapes and sizes have larger than erythrocytes. Leukocytes have a nucleus round and concave. These cells can move freely in amuboid and can penetrate the capillary wall (diapedesis).
Leukocytes can be divided into two, namely leukocyte granulocytes (granular plasma = basophils, eosinophils, neutrophils) and leukocytes agranulosit (not plasma = granular lymphocytes, monocytes)
The formation and function of White Blood Cells
Granulocytes and monocytes have an important role in protecting the body against microorganisms. With the ability as phagocytes (Fago-consuming), they eat live bacteria that enter the circulatory system.
through a microscope can sometimes be found as much as a 10-20 microorganisms ingested by granulocytes. at the time they perform this function are called phagocytes. the strength of the amuboid movement he can move freely inside and can get out and walk around the blood vessels throughout the body.
Surrounded the affected area of infection or injury, capture capture organisms and destroy, get rid of other materials such as dirt, and other debris, in the same way, and as granulocytes have enzymes that can break down proteins, which allows damaging living tissue, destroying and throw. in this way are sick or injured tissue can be removed and healing is possible As a result of the work of phagocytic white blood cells, inflammation can be stopped altogether.
Pus Store “corpse” of friends and enemies – who were killed in the performance phagocytes called pus cells. There are so many germs are dead in the pus and coupled with a large number of networks that have been melted. and pus cells will be eliminated by a healthy granulocyte working as phagocytes.
