C6.2: Immunity-3rd line of defense Flashcards
The scientific study of the immune system and immune
responses
immunology
Is a condition of being immune or resistant to a particular
infectious disease
immunity
What are the Primary function of Immune System
1.Differentiate between “self and non self” (something foreign)
2.Destroy that “non self”
Always involves
the production of
antibodies
Humoral immunity
_______ play a
major role in
humoral immunity
Antibodies
Involves many different cell types,
including macrophages, T helper
cells, cytotoxic T cells, delayed
hypersensitivity T cells, natural
killer cells, killer cells and
granulocytes
Cell mediated immunity
refers to the process of
exposing the body to an antigen to generate an adaptive
immune response: the response takes days/weeks to
develop but may be long lasting even lifelong.
Active acquired immunity
refers
to the process of providing IgG
antibodies to protect against infection; it gives immediate, but
short lived protection several weeks to 3 or 4 months at most.
Passive acquired immunity
Immunity
that is acquired in
response to the entry of a live
pathogen into the body (i.e., in
response to an actual infection)
Natural Active
Acquired Immunity
Immunity
that is acquired in response
to vaccines
Artificial Active
Acquired Immunity
Immunity
that is acquired by a
fetus when it receives maternal
antibodies.
Natural passive
Acquired Immunity
Immunity
that is acquired when a
person receives antibodies contained in
antisera or gamma globulin
Artificial passive
Acquired Immunity
Defined as the material
that can artificially induce
immunity to an infectious
disease, usually after
injection or, in some cases,
ingestion of the material.
vaccine
are foreign
organic substances that are
large enough to stimulate
the production of
antibodies; antibody
generating substance.
Antigens
Substances that are
capable of stimulating the
production of antibodies are
called ___.
antigenic
