Immune System
Caused by progens
Summarized as "eaten and digested"
redness, heat, swelling, and pain
NK cells
a special type of lymphocyte that acts nonspecifically to destroy certain cells
protective proteins
complement and interferons
mechanical barriers
first line of defense that includes an intact skin and mucous membrane
chemical barriers
first line of defense that includes tears, saliva, hydrochloric acid, and perspiration
plasma cells
a subgroup of the B cell clone that secrets antibodies
recognition of self
the cell responsible for antigen presentation
antibody-mediated immunity
also called humoral immunity
cell-mediated immunity
T cell immunity
Complement and interferons are
protective proteins engaged in nonspecific immunity
Plasma cells
secrete antibodies
What is the primary concern regarding the care of a person experiencing an anaphylactic reaction
the inability to breathe
Which of the followin is least true of or related to a vaccine?
passive, immediate onset, and short-lived immunity
Inflammation is
characterized by redness, heat, swelling, and pain
Leukocytosis is generally an dndication
that the WBC's are engaging in phagocytosis
Which of the following is the least true of the kupffer cells?
engage in antibody-mediated immunity
The redness and heat of inflammation is caused by
A person has an infection and his phagocytes respond appropriately by releasing pyrogens, thereby resetting the body's thermostat. What happens next?
he shivers, thereby producing heat.
When activated, this protective protein swarms over the bacerium, punching holes in its membrane and increasing its susceptibility to phagocytosis
This member of the T cell clone destroys the bacterium by pumching holes in its cell memebrane and by secreting lymphokines that enhance phagocytic activity
killer T cells
Helper T cells
secrete a hymphokine that stimulates B and T cells activity and, in general enhance the immune response
Human immunodeficiency virus (HIV) attacts the helper T cells, thereby
Making the person more susceptible to infection
attack antigens
The CD4+ T cell is a
helper T cell
An antigen-antibody ineraction
causes agglutination
If you have a high measles antibody titer, you
must have had measles as a child
Which of the following is a marker for immune function and is used to monitor the progession of HIV infection?
CD4+ T cell count
The administration of tetanus toxoid
Conveys short-lasting passive immunity
Which of the following is true of naturally acquired active immunity
"Getting the disease" as a child conveys this type of immunity
With which of the following is an immediate hypersensitivity reaction most associated?
Which of the following stimulates memory cells to produce antibody-secreting plasma cells?
a booster shot
IgE antibodies
bind to mast cells, liberating histamine
The release of histamine is of concern because it
constricts breathing passages
A drug that_________ would be most useful in the treatment of anaphylactic shock.
relaxes the smooth muscles of the respiratory passages
