| | Term | Definition |
|---|---|---|
| |
Pathogen | A disease causing organism or virus |
| |
Infectious disease | A disease caused by a pathogen |
| |
Nonspecific defense | physical or chemical barrier that prevents pathogens from entering the body |
| |
Inflammatory response | nonspecific defense against infection, characterized by redness, heat, swelling, and pain |
| |
Histamine | chemical alarm signal released by mast cells that causes blood vessels to dilate during an inflammatory response |
| |
Interferon | protein produced by cells in response to being infected by a virus; helps other cells resist the virus |
| |
Immunity | Resistance to a specific pathogen |
| |
Antigen | foreign molecule that provokes an immune response |
| |
Antibody | protein in blood plasma that attaches to a particular antigen |
| |
B cell | lymphocyte that matures in the bone marrow and later produces antibodies; responsible for humoral immunity |
| |
T cell | lymphocyte that matures in the thymus; is responsible for cell-mediated immunity and also plays a role in humoral immunity |
| |
Plasma cell | antibody-secreting B cell |
| |
Humoral Immunity | specific immunity produced by B cells that produce antibodies that circulate in body fluids |
| |
Cell-mediated immunity | type of immunity produced by T cells that attack infected or abnormal body cells |
| |
Cytotoxic T cell | lymphocyte that attacks body cells infected with pathogens |
| |
Helper T cell | lymphocyte that activates cytotoxic T cells and stimulates B cells to produce antibodies |
| |
Memory Cell | long-lasting lymphocyte formed during the primary immune response that is reactivated on exposure to the same pathogen, quickly producing many clones |
| |
Vaccine | dose of a disabled or destroyed pathogen (or part of a pathogen) used to stimulate a long-term immune defense against the pathogen |
| |
Active immunity | immunity provided by the body producing its own antibodies against a particular antigen; results from exposure to the antigen via infection or vaccine |
| |
Passive immunity | resistance to a particular pathogen that results when the body acquires antibodies for it, as when a baby receives antibodies from its mother |
| |
Allergy | abnormal immune system sensitivity to an otherwise harmless antigen |
| |
Autoimmune disease | disorder in which the immune system attacks the body's own molecules |
| |
AIDS | acquired immune deficiency syndrome; the late stages of HIV infection |
| |
HIV (human immunodeficiency virus) | virus that destroys helper T cells and causes AIDS |
