Granulocyte

Granulocytes (singular: the granulocyte, from Latin granule " grains " and ancient Greek κύτος CYTOS " hollow ", " vessel ", "shell" ), and polymorphonuclear leukocytes ( from Ancient Greek πολύ poly " many", ancient Greek μορφή morph "form", ancient Greek λευκός leukos "white" and an ancient Greek κύτος CYTOS " hollow ", " vessel ", "shell" ) called, are a type of white blood cells. They account for 45-75 % of all leukocytes. Granulocytes are formed in the bone marrow and released into the blood. The lifespan of basophils is about seven days, the neutrophil 1-4 days. The reduction of granulocytes occurs in mononuclear Phagozytosesystem (monocytes ). You can leave the bloodstream and migrate into tissue. Their function is mainly due to the non-specific defense ( innate immune response) of bacteria, parasites and fungi. Some granulocytes are able to take up pathogens and destroy. These are therefore counted as " phagocytes ".

There are neutrophils, basophils and eosinophils, which are described and divided depending on the dyeing behavior of the protoplasm. They each have different functions.
