The Body`s Defenses
... When the body is invaded, four important nonspecific defenses take action: the inflammatory response; the temperature response; proteins that kill or inhibit pathogens; and white blood cells, which attack and kill pathogens. Inflammatory Response: Injury or local infection, such as a cut or a scrape ...

Lymphopoiesis
Lymphopoiesis (lĭm'fō-poi-ē'sĭs) (or lymphocytopoiesis) is the generation of lymphocytes, one of the five types of white blood cell (WBC). It is more formally known as lymphoid hematopoiesis.Pathosis in lymphopoiesis leads to any of various lymphoproliferative disorders, such as the lymphomas and lymphoid leukemias.
