WGU Clinical Microbiology Final Exam
With Answers.
Antigen - ANSWER- A substance the body identifies as foreign and causes an immune
response.
Antibody - ANSWER- A protein produced in response to an antigen that is capable of
binding specifically to the antigen.
Innate immunity - ANSWER- Exists because of genetically determined characteristics.
Naturally acquired
immunity - ANSWER- Having a specific disease
Artificially acquired adaptive immunity - ANSWER- Receiving an antigen by injection of
vaccine or immune serum that produced immunity.
Naturally acquired active immunity - ANSWER- produced when a person is exposed to
an infectious agent.
Naturally acquired passive immunity - ANSWER- produced when antibodies made by a
mother's immune system are transferred to her off spring.
B lymphocytes (B cells): - ANSWER- secrete antibodies.
Plasma cells: - ANSWER- develop from activated B cells. Helps produce large amounts
of a specific antibody.
Memory B cells: - ANSWER- remember the same pathogen for faster antibody
production in future infections.
T cells: - ANSWER- directly attack foreign substances, increase B cell response, and
produce cytokine that direct responses and activities in other immune cells.
Helper T cells: - ANSWER- increase the immune response by recognizing the presence
of a foreign antigen and then stimulating antibody production and producing cytokines
that "turn on" or activate other T cells.
Cytotoxic T cells: - ANSWER- Killer cells. Directly attack and destroy cells with antigenic
material.
Which type of cells produce antibodies? - ANSWER- B cells (lymphocytes)
