Lupus erythematosus is an autoimmune disorder in which the body attacks -
ANSWER-its own connective tissue.
T/F: A "stitch" in the side experienced during vigorous exercise is due to the
contraction of the liver as it releases additional blood into the bloodstream. -
ANSWER-False
T/F: Histamine is released by neutrophils to induce an inflammation response when
tissues become damaged. - ANSWER-False
T/F: Tears and saliva contain the enzyme dermicidin, which is effective in preventing
bacteria from entering the human body. - ANSWER-False
T/F: The first type of white blood cell to arrive at the site of an infection is the
eosinophil. - ANSWER-False
T/F: Indicators of "self" to your immune system are referred to as MHC proteins. -
ANSWER-True
T/F: The best way to defend the body from a viral infection is to prevent the infection
by using a vaccine. - ANSWER-True
T/F: When considering transfusions or transplants, it is more difficult to match blood
than to match tissue types because blood cells have more self-markers on their
surface. - ANSWER-False

body a second time. - ANSWER-Memory
B lymphocytes mature in ________. - ANSWER-Bone marrow

respond by releasing histamine. - ANSWER-Mast
Chemicals released by macrophages that cause the onset of a fever are called
________. - ANSWER-Pyrogens
, An antibody response to the second exposure to antigen differs from the response to
the initial antigen encounter in that - ANSWER-the response is more rapid, longer
lasting and is larger by comparison to the initial encounter.
Which of the following types of T cells is a critical component of the immune system
because it stimulates and enhances the activity of other components of the immune
system? - ANSWER-T helper cell
Which of the following best explains why people get so many colds in their lifetime? -
ANSWER-The viruses that cause colds evolve rapidly, which results in a change in
their antigenic structure.
Vaccines contain - ANSWER-antigens of the pathogen.

referred to as - ANSWER-an allergen.
Passive immunity differs from active immunity in that passive immunity - ANSWER-
involves the administration of preformed antibodies.

antibodies across the placenta from mother to child
HIV is classified as a retrovirus because - ANSWER-it makes a DNA copy of its RNA
once inside the host cell.
Antibiotics kill bacterial cells but do not (usually) damage human cells by taking
advantage of the difference between human and bacterial cells. These differences
include - ANSWER-bacterial cells have cell walls, human cells do not.
Cell-mediated immunity involves the activity of ________ lymphocytes. - ANSWER-T
