,Th2 cells produce IL-4 and suppress which cells? a. B
lymphocytes b. Cytotoxic T lymphocytes c. Th1 cells
d. Memory T lymphocytes - ANSWER-C. Th2 cells
produce IL-4, which suppresses only Th1 and Th17
cells through their IL-4 receptors.
Which action is a purpose of the inflammatory
process? a. To provide specific responses toward
antigens b. To lyse cell membranes of
microorganisms c. To prevent infection of the injured
tissue d. To create immunity against subsequent
tissue injury - ANSWER-C. If the epithelial barrier is
damaged, then a highly efficient local and systemic
response (inflammation) is mobilized to limit the
extent of damage, to protect against infection, and
to initiate the repair of damaged tissue. The
response to a specific offending agent is the function
of the adaptive immune response. Lysosomes lyse
cell membranes. Immunity against a subsequent
,tissue injury occurs through the action of B cells and
T cells.
What causes the edema that occurs during the
inflammatory process? a. Vasodilation of blood
vessels b. Increased capillary permeability c.
Endothelial cell expansion d. Emigration of
neutrophils - ANSWER-B. The increased flow and
capillary permeability result in a leakage of plasma
from the vessels, causing swelling (edema) in the
surrounding tissue and is solely responsible for
inflammation-induced edema.
Vasodilation (increased size of the blood vessels)
causes slower blood velocity and increases blood
flow to the injured site. Endothelial cell contraction
(not expansion) leads to increased capillary
permeability. Emigration of neutrophils to the area
of infection/injury leads to increased destruction of
the offending agent.
, What plasma protein system forms a fibrinous
meshwork at an inflamed site? a. Complement b.
Coagulation c. Kinin d. Fibrinolysis - ANSWER-B. The
coagulation (clotting) system is a group of plasma
proteins that form a fibrinous meshwork at an
injured or inflamed site. This protein system (1)
prevents the spread of infection to adjacent tissues,
(2) traps microorganisms and foreign bodies at the
site of inflammation for removal by infiltrating cells
(e.g., neutrophils and macrophages), (3) forms a clot
that stops the bleeding, and (4) provides a
framework for future repair and healing.
Which component of the plasma protein system tags
pathogenic microorganisms for destruction by
neutrophils and macrophages? a. Complement
cascade b.
Coagulation system c. Kinin system d. Immune
system - ANSWER-A. C3b (a component of the
complement cascade) adheres to the surface of a
pathogenic microorganism and serves as an efficient
