natural immunity (innate or native)
CORRECT ANSWER:
type of immunity that includes physical barriers (e.g., skin),
phagocytic cells, and natural killer cells. All of these factors are
present before exposure to a particular infectious agent, and all
respond nonspecifically.
specific acquired immunity
CORRECT ANSWER:
Immunity in which responses occur only after exposure to a foreign
substance. Objective is to destroy antigens
Antigens
CORRECT ANSWER:
The foreign substances that induce specific responses in specific
acquired immunity
Cell-mediated, Humoral (antibody-mediated)
CORRECT ANSWER:
the two classes of specific acquired immunity
Cell-mediated immunity
,CORRECT ANSWER:
refers to immune responses in which targets are attacked directly by
immune system cells—specifically, cytolytic T cells and
macrophages
Humoral immunity
CORRECT ANSWER:
refers to immune responses that are mediated by antibodies.
B lymphocytes
CORRECT ANSWER:
have the job of making antibodies. Hence mediates humoral
immunity. produced in the bone marrow.
Cytolytic T Cells
CORRECT ANSWER:
attack and kill target cells directly, mature in the thymus
Helper T cells
CORRECT ANSWER:
contribute to the immune response in three ways: (1) they have an
essential role in antibody production by B cells; (2) they release
factors that promote type IV sensitivity reactions, also known as
delayed-type hypersensitivity (DTH); and (3) they participate in the
activation of cytolytic T cells.
Are the immune cell that HIV attacks
Mature in the thymus
Macrophages
CORRECT ANSWER:
Present in all organs and tissues, primary role is phagocytosis, (1)
they are required for activation of T cells (both helper T cells and
,cytolytic T cells), (2) they are the final mediators of DTH, and (3) they
phagocytize cells that have been tagged with antibodies
Dendritic Cells
CORRECT ANSWER:
perform the same antigen-presenting task as do macrophages, but
do not act as scavengers
Mast cells
CORRECT ANSWER:
These cells mediate immediate hypersensitivity reactions, derived
from basophils, concentrated in the skin and other soft tissues,
release histamine, heparin, and other compounds that cause the
symptoms of immediate hypersensitivity
Basophils
CORRECT ANSWER:
These cells mediate immediate hypersensitivity reactions, circulate
in the blood, release histamine, heparin, and other compounds that
cause the symptoms of immediate hypersensitivity
Neutrophils
CORRECT ANSWER:
phagocytize bacteria and other foreign particles, avidly devour cells
that have been tagged with antibodies of the immunoglobulin G (IgG)
class, major contributors to inflammation
Eosinophils
CORRECT ANSWER:
attack and destroy foreign particles that have been coated with
antibodies of the IgE class. Their usual target is helminths (parasitic
worms). also contribute to tissue injury and inflammation associated
with immediate hypersensitivity reactions.
, Antibodies
CORRECT ANSWER:
are a family of structurally related glycoproteins that mediate
humoral immunity. The most characteristic feature is their ability to
recognize and bind with specific antigens.
Immunoglobulins and globulins.
CORRECT ANSWER:
Alternative names for antibodies are
B lymphocytes
CORRECT ANSWER:
all antibodies are produced by
IgA
CORRECT ANSWER:
located in mucous membranes of the GI tract and lungs and in many
secretions, serve as the first line of defense against microbes
entering the body via these routes, transferred to infants via
breastmilk (not absorbed in the GI tract, but does protect the infant
from microbes in the GI tract)
IgD
CORRECT ANSWER:
found only on the surface of mature B cells where it serves as a
receptor for antigen recognition (along with IgM)
IgE
CORRECT ANSWER:
bind to the surface of mast cells, stimulating the release of
histamine, heparin, and other mediators from the mast cell causing
