GRADED A+ FOR PASS
A primary effector cell of the type I hypersensitivity response is
- monocytes.
- mast cells.
- neutrophils.
- cytotoxic cells. - CORRECT ANSWERS mast cells
Mast cells are a primary effector cell of the type I hypersensitivity response.
Monocytes, neutrophils, and cytotoxic cells are not primary effectors of the type I
hypersensitivity response.
When mast cells degranulate, they release:
- perforins and other toxins.
- histamine and other inflammatory mediators.
- complement.
- antibodies. - CORRECT ANSWERS histamine and other inflammatory
mediators.
Mast cells release inflammatory mediators such as histamine when they
degranulate.
How does a cytotoxic T lymphocyte kill another cell?
- By secreting cytokines that attract phagocytes
- By producing antibodies that opsonize it

- By phagocytizing it directly
- By secreting perforins and granzymes - CORRECT ANSWERS By secreting
perforins and granzymes
Cytotoxic T lymphocytes secrete perforins and granzymes that cause cell death.
The process of covering bacteria with antibodies to promote phagocytosis of the
microorganisms is called:
- neutralization.
- precipitation.
- margination.
- opsonization - CORRECT ANSWERS opsonization
The Fc portions of the antibodies that cover an opsonized microorganism attract
phagocytes.
The predominant antibody of a typical allergic response is:
- IgG.
- IgM.
- IgE.
- IgA. - CORRECT ANSWERS IgE

(IgA is the predominant antibody in mucosal membrane secretions.)
Which of the following cells produce antibodies?
- T cells
- Mast cells
- Plasma cells
- Macrophages - CORRECT ANSWERS Plasma cells
Plasma cells are mature B lymphocytes that have developed the capacity to
produce antibodies during an immune response.
Severe combined immunodeficiency (SCID) syndrome is an example of a(n)
- deficient immune response.
- excessive immune response.
- primary acquired immunodeficiency.
- hypersensitivity reaction. - CORRECT ANSWERS deficient immune
response.
SCID syndrome is an example of a deficient immune response in which the
immune response is ineffective because of disease-causing genotypes or
secondary/acquired dysfunction. An excessive immune response includes
disorders in which the immune system is overfunctioning or hyperfunctioning.
