They are formed by the process known as [[leukopoiesis|leukopoiesis]]. Leukocytes are sub divided into granulocytes and agranulocytes; granulocytes have a granular cytoplasm and polymorphic nuclei such as is seen in [[Neutrophils|neutrophils]], [[Eosinophils|eosinophils]], and [[Basophils|basophils]]. Granulocytes function as part of the non specific natural immune response to infection and as part of the inflammatory response to tissue injury. |
| + | |
| + | The agranulocytes include [[Lymphocytes - Introduction|lymphocytes]] and [[Monocytes|monocytes]]. Lymphocytes differ from granulocytes and monocytes as they form part of the acquired immune response, dividing into B or T cells to fight attacks by foreign cells, bacteria and viruses. Monocytes leave the blood stream to enter tissues where they become [[Macrophages|macrophages]], which engulf bacteria and tissue debris by phagocytosis. |
