What is immunology? - (correct Answer) - The study of an organism's immune system - specifically how it
defends the organism against infection and how it responds to/consequences of incorrect immune
responses.
What is innate immunity? - (correct Answer) - A set of mechanisms (present from origin) present at all
times in all individuals (constant). Mechanisms lead to the recognition and response to the presence of a
pathogen.
- NON SPECIFIC!
What is acquired/adaptive immunity? - (correct Answer) - A SPECIFIC immune response mediated by
antigen-specific lymphocytes toward a specific antigen. (associated with immunologic memory)
What is an antigen? - (correct Answer) - Any molecule which can bind specifically to an antibody
What is an immunogen? - (correct Answer) - Any antigen which can induce antibody production
"Antibody Generators"
What is an antibody? - (correct Answer) - A protein which is produced by plasma cells in response to
infection or immunization which binds specifically to its corresponding antigen.
What is meant by an immunoglobulin? - (correct Answer) - Immunoglobulin is a general name for
antibody because they all have the same overall structure
where are antibodies found? - (correct Answer) - In clear, yellowish fluid in blood (SERUM).
What are the two arms of acquired immunity? - (correct Answer) - - cell mediated immunity
-humoral immunity
What is humoral immunity? What type of cells does it use? - (correct Answer) - The immune response
raised to eliminate extracellular pathogens (uses antibodies)
It is mediated by B cells and T helper cells
What is cell mediated immunity? What type of cells does it use? - (correct Answer) - -The immune
response raised to eliminate abnormal cells and intracellular pathogens
-It uses cytotoxic T cells.
What is a lymphocyte? - (correct Answer) - a type of white blood cell involved in the immune response
What is a plasma cell & what are they responsible for? - (correct Answer) - A differentiated B lymphocyte
responsible for antibody production.
What is a B memory cell & what do they do? - (correct Answer) - A differentiated B lymphocyte that
