Three primary protective functions of the immune response -
correct answer -1. protects the body from invasion of
microorganisms and other antigens
2. removes dead or damaged tissue and cells
3. recognizes and removes cell mutations that have demonstrated
abnormal cell growth and development
First line of defense - correct answer -skin bounding surfaces
such as: mucous membranes, enzymes, natural microbial flora,
and complement proteins
Second line of defense - correct answer -accomplished by the
activities of phagocytes, natural killer T lymphocytes,
granulocytes, and macrophages providing innate, nonspecific
immunity
, Page | 2
Third line of defense - correct answer -comes from antibodies
derived from B lymphocytes and T lymphocytes resulting from
learned or acquired specific immunity
Immunocompromised - correct answer -individuals who have
suppressed immune responses
Primary immunodeficiency - correct answer -situation when
entire immune defense system is inadequate and the individual is
missing some if not all of the components necessary for a
complete immune response
Secondary immunodeficiency - correct answer -a loss of immune
function (in a person with previously normal immune function) as
a result of an illness or treatment
Inflammation - correct answer -an immunologic defense against
tissue injury, or allergy
Acute inflammation response - correct answer -immediate
response to tissue injury and is short in duration (minutes-days)
, Page | 3
Chronic inflammation response - correct answer -inflammation
that continues for weeks to years after initial injury
Infection - correct answer -invasion and multiplication of
microorganisms in body tissues
Pathogen - correct answer -microorganisms that cause human
disease
Bacteria - correct answer -one-celled organism without true
nucleus or cellular organelles
Virus - correct answer -pathogen with an nucleic acid within a
protein shell and requires invasion of a host for replication
Acute infection - correct answer -resolve in a few days or weeks
, Page | 4
Chronic infection - correct answer -lasts (typically) longer than
12 weeks and in some cases is non-curable
Localized infection - correct answer -limited to a specific body
area
Systemic infection - correct answer -infection that affects the
body as a whole or has spread throughout the body
Disseminated - correct answer -used to describe a spread of
infection from an initial site to other areas of the body
Sepsis - correct answer -common type of systemic infection, is
the presence of pathogens in the blood or other tissues
throughout the body
Epidemic - correct answer -a situation in which there are more
cases of infectious disease than is normal for the population or
geographic area
