Document Summary

Inflammation: immune response of the body to damaged tissues or infections characterized by swelling, pain, heat, and/or redness. Phagocytes: immune system cells that eat antigens, eg. neurtophils, monocytes. Macrophages: monocytes that become enlarged upon leaving the bloodstream and entering bodily tissue. Natural killer cells: lymphocytic cells programmed to recognize other cells that are non-self and cells infected with viruses and to release cytotoxic chemicals that lyse these cells. T-cells: lymphocytic cells that develop in the thymus. B-cells: lymphocytic cells that develop in the bone marrow that produce antibodies. Lymphocytes: a category of immune system cells that include natural killer cells, t cells, and b cells. Immunoglobulins: antibodies; soluble proteins produced by b-cells that circulate in the bloodstream and bind to viruses and other antigens to neutralize them. Cellular mediated immunity: defence system employed by our immune system involving natural killer cells, the granulocytes (e. g. , neutrophils), the macrophages, and t cells inflaming, phagocytosing, and releasing toxic substances.
