Immune System 1
provides a specific reaction to each invading antigen and has the unique ability to remember the antigen that caused the attack.
Adaptive Immunity
a substance that can produce a hypersensitive reaction in the body is not necessarily inherently harmful
Allergen
an acute and potentially fatal hypersensitivity (allergic) reaction to an allergen.
Anaphylactic Shock
the study of the immune system
Immunology
an abnormal condition of the immune system in which cellular or humoral immunity is inadequate and resistance to infection is decreased
Immunodeficiency
the ability of an immune system to mobilize and deploy its antibodies and other responses to stimulation by an antigen.
Immunocompetence
an abnormal condition characterized by an excessive reaction to a particular stimulus.
Hypersensitivity
the administration of agents that significantly interfere with the ability of the immune system to respond to antigenic stimulation by inhibiting cellular and humoral immunity.
Immunosuppressive
a process by which resistance to an infectious disease is induced or increased.
Immunization
the process of weakening the degree of virulence of a disease organism.
Attenuated
something that has its origin within an individual, especially a factor present in tissues or fluids
Autologous
removal of plasma that contains components causing or thought to cause disease. Also called exchange because when the plasma is removed, it is replaced by substitution fluids such as saline or albumin.
Plasmapheresis
one of the two forms of immunity that responds to antigens, such as bacteria and foreign tissue; it is mediated by B cells
Humoral immunity
any agent or substance capable of provoking an immune response or producing immunity.
Immunogen
Antiodies form naturally after____
Antibodies form artificially after____
infection
vaccinations
a special treatment of allergic responses; involves the administration of increasingly larger doses of the offending allergens to gradually develop immunity.
Immunotherapy
the mechanism of acquired immunity characterized by the dominant role of small T cells; also called cell-mediated immunity
Cellular immunity
List an example for each of the three functions of the immune system
Natural barriers (skin and mucous membranes) protect the internal environment. Phagocytes provide homeostasis by removing damaged cells from circulation. Antibodies are formed to recognize and destroy abnormal cells.
a substance recognized by the body as foreign that can trigger an immune response.
Antigen
one of the chemical factors produced and released by T cells that attract macrophages to the site of infection or inflammation and prepare them for attack.
Lymphokine
pertains to the development of an immune response to one's own tissue.
Autoimmune
A disorder in which the body produces its own antigens; failure to distinguish self from non-self.
What is the definition of an autoimmune disorder
the body's first line of defense; provides physical and chemical barriers to invading pathogens and protects the body against the external environment.
Innate immunity
reproduction or multiplication of similar forms.
Proliferation
the quality of being insusceptible to or unaffected by a particular disease or condition
Immunity
