Describe how natural and aquired immunity work within the body | Natural immunity: provides a barrier against invaders and nonspecific immunity to the individual
Aquired immunity: Provides a specific reaction to invaders and remembers the antigen that caused the attack. |
How is cell-mediated immunity achieved? | By activation of T cells. |
What happens to sensitized T cells | They are released into the blood and body tissues |
What is the significance of cell-mediated immmunity? | To distinquish between self and foreign antigens |
What type of cells initate antibody production? | B-cells. |
What is active immunity? Provide an example | Antibodies produced by ones own body

Which cells mediate humoral immunity? | The B cells |
What is released in an antigen-antibody reaction? | Histamine |
To what type of antigens does humoral immunity respond? | Bacteria foreign tissue |
The pt. has asked the nurse to explain the difference between immunocompetency, immunodeficiency & autoimmunity. How will the nurse explain the difference in terms she will understand? | Immunocompetency means the body is healthy enough to fight off an infection without help
Immunodeficiency: THe body is unstable and cannot fight off an infection
Autoimmunity: The body turns on itself and begins to fight off normal bacteria in the body |
Describe how immunization and immunotherapy can be used to help the body develop immunity | Immunizations control exposure to a disease to produce antigens while preventing the actual disease.
