How Does Intrinsic Immune System Play Function?

The function of intrinsic immune system is based on the large quantity of immunocytes. Which can be divided into two kinds: one is phagocyte and the other one is Killer Cell. These two kinds of immunocytes have different functions when they are working normally. Phagocyte play its function by swallowing pathogenic factors in blood or body tissue and then digesting thee pathogenic factors gradually. Killer Cell plays its function in two parts. One is to kill cells that are affected by virus and it can also kill some cancer cells; the other function is to degrade relative large pathogenic factors that phagocyte can not swallow, which is helpful for phagocyte to play their function. Through this way, pathogenic factors in blood and body tissue can be eliminated more effectively, thus protecting the blood and body tissue in a clean condition.
Phagocyte cells can be divided into mononuclear phagocyte and multinuclear phagocyte according to the different karyomorphism. Mononuclear phagocyte includes mononuclear cell and macrophage which are both originated from bone marrow and all have the specific feature of phagocyte. However, mononuclear cell only exist in blood, but macrophage can be find in various body organs. Expert studied that there is also macrophage in kidneys.
Multinuclear phagocyte contains three kinds: Eosnophils which is especially to phagocytize eosinophilic dyes as well as parasitic infection and to join adaptive immune response; basophiles which plays function of phagocytizing basophilic dyes and joining the anaphylaxis of adaptive immune response; neutrophil that has strong effect on eliminating bacteria through phagocytizing bacteria and other pathogenic microorganism.
The above two kinds of immunocytes forms a huge phagocyte system, playing the function of maintaining blood clean, tissue clean as well as lymphatic system clean and body health condition.
