Chapter 21 Anatomy immune system
which of the following is NOT a step in t cell activation?
production of antibody secreting plasma cells
Which of the following words means fever producing?
pyrogenic
antibodies
(all of the above) include IgG, IgM, and IgE are secreted by plasma cells react with antigens causing agglutination
which of the following is true of the Tcell?
(all of the above) it is activated in response to a specific antigen it engages in cell mediated combat its clones include killer t cells, helper tcells, suppressor t cells, and memory t cells
HIV attacks the helper t cells thereby
(all of the above) depressing t cell function making the person more susceptible to infection depressing b cell function
inflammation is
characterized by redness, swelling, heat and pain
which group is incorrect?
chemical barriers: tears, saliva, stomach acid, b cells, t cells
Which of the following is characterized by a local tissue response to t cell activity?
contact dermatitis
a vaccine
conveys active immunity
the kupffer cells are fixed macrophages within the walls of the hepatic sinusoids and
engage in phagocytosis of pathogens in the blood coming from the organs of digestion
Which of the following is the treatment of choice for an anaphylactic reaction?
epinephrine and steroid
which of the following is true of Kupferr cells?
fixed macrophages
if you have high measles antibody titer, you
have been exposed to the measles virus
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
binding of the bee venom allergen to antibodies on the mast cell causes a massive release of which substance?
histamine
what is the term that refers to the use of dead of attenuated pathogens to stimulate antibody production?
immunization
memory cells
increase the response time to an antigen
a booster
increases antibodies to an antigen
which of the following conditions is most common in people with AIDS
infections
redness, heat, swelling, and pain are indicative of
inflammation
which of the following describes the effects of phagocytosis
ingestion and destruction of pathogens and other foreign substances
the plasma cells are least related to
interferons
which of the following are classified as killer, helper, suppressor, and memory?
T cells
which cell engages in cell-to-cell combat?
Tcell
Which of the following is true of the B cell?
activated in response to a specific antigen
what is the name of a severe hypersensitivity reaction?
anaphylaxis
an allergen is a
antigen
agglutination is the consequence of
antigen antibody reaction
plasma cells
are b cell clones
the redness and heat associated with inflammation
are due to the release of histamine from injured tissue; it dilates blood vessels and increases blood flow to the inflamed area
complement and interferons
are protective proteins that enhance the immune response to infection
this is a group of proteins secreted by virally infected cells; the proteins prevent viral replication
interferons
which of the following represents specific immunity?
b and t cells
An antigen-antibody interaction
causes agglutination
which of the following is true of activation of mast cells
causes the release of histamine
A febrile seizure is a seizure that
is caused by a fever
which of the following is true about nonspecific immunity?
it includes processes such as inflammation phagocytosis and fever
which of the following t cells destroy pathogens by punching holes in their cell membrane and secreting lymphokines?
killer
which of the following cells engulf the pathogen to achieve antigen presentation?
macrophages
the purpose of vaccination is to provide an initial exposure to an antigen to stimulate the formation of
memory cells
which of the following t cells do not participate in the destruction of the pathogen but allow for a more rapid response if the antigen is presented at a later time
memory t cells
if you had measles as a child, which of the following best describes your immunity to measles?
naturally aquired active immunity
a breast fed infant is initially immune to the same diseases as her mom. which of the following describes the infant's immunity?
naturally aquired passive immunity
which of the following is most related to the placental transfer of antibodies from the mother to the fetus?
naturally aquired passive immunity
which group is incorrect?
nonspecific immunity: inflammation, NK cells, fever, Tcells
which of the following is most related to antibody mediated immunity?
plasma cells
what is the primary concern regarding the care of a person experiencing an anaphylactic reaction?
the inability to breathe
which of the following best explains the secondary response to a booster shot?
the presence of memory cells that can quickly produce plasma cells
what is the name of the toxin that has been altered so that it is harmless yet still antigenic?
toxoid
which of the following best describes an abscess?
walled off area of dead cells and their secretions
