What are the main function of leucocytes |
|
Answer» Answer: LEUKOCYTES are the major cellular components of the INFLAMMATORY and immune system. While they only make up about 1 percent of the blood in the body, leukocytes play an important role in protecting the body from infections/diseases caused by various microorganisms (e.g. bacteria, amoeba etc) and other types of parasites (filarial worms etc). Moreover, they are involved in various allergic reactions and contribute to the repair of damaged tissue as well as the elimination of tumorous cells. In some cases, however, leukocytes may be the cause of diseases as is the case with autoimmune diseases and non-hemolytic transfusion reactions in human beings. Depending on whether they contain granules or not, there are TWO major types of leukocytes that can be found in blood, cerebrospinal fluid as well as various body TISSUES where they remain for several hours or a few days depending on the TYPE of cells. |
