| anaphylactic shock |
shock resulting from a severe allergic reactions, may be fatal |
| B-cell |
a lymphocyte; activated B cells develop into plasma cells, which secrete antibodies into the blood |

| complement |
any of several inactive enzymes normally present in blood, which, when activated, kill foreign cells by dissolving them |
| complement cascade |
rapid fire series of chemical reactions involving proteins called complements, which are triggered by certain antibody-antigen reactions, and resulting in the formation of tiny protein rings that create holes in a forgein cell and cause its destruction |
| humoral immunity |
immunity that is produced when antibodies make antigens unable to harm the body |
| inflammatory response |
nonspecific immune process produced in response to injury and resulting in redness, pain, heat, and swelling and promoting movement of white blood cells to the affected area |

specialized fluid formed in the tissue spaces that returns excess fluid and protein molecules to the blood |
| macrophage |
phagocytic cells in the immune system |
| memory cells |
cells that remains in the reserve in the lymph nodes until its ability to secrete antibodies is needed |
| monoclonal antibodies |
specific antibody produced from a population of identical cells |
| nonspecific immunity |
protective mechanisms that provide immediate, generic protection against any bacteria, toxin, or other injurious particle |
| plasma cells |
cells that secrete copious amounts of antibody into the body |
| specific immunity |
protective mechanisms that provide specific protection against certain types of bacteria or toxins |
