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 first layer of defense against infection.
What is skin?
an abnormal condition of the immune system in which cellular or humoral immunity is inadequate and resistance to infection is decreased
Immunodeficiency
We do this frequently to keep our skin clean to prevent the spread of germs.
What is wash our hands?
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
What percentage of bacteria in your body is good?
99%
Glands that collect and eliminate bacteria and viruses.
What are lymph node glands?
This is an example of an autoimmune disease
What is type 1 diabetes?
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
Two types of lymphocytes
What are T cells and B cells?
Antiodies form naturally after____
Antibodies form artificially after____
infection
vaccinations
Kills body cells that have foreign antigens being presented on the cell surface
Killer T cell
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
Thick substance that catches microbes before entering the body
Mucous
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
provides physical and chemical barriers to invading pathogens and protects the body against the external environment.
the body's first line of defense;
A disease caused by a pathogen
Infectious disease
