1. The principal function of the immune system is:

a. Defense against cancer pc pc


b. Repair of injured tissues pc pc pc


c. Defense against microbial infections pc pc pc


d. Prevention of inflammatory diseases pc pc pc


e. Protection against environmental toxins pc pc pc




ANS: C p c


The immune system has evolved in the setting of selective pressures imposed by microbia
pc pc pc pc pc pc pc pc pc pc pc pc pc


l infections. Although immune responses to cancer may occur, the concept that ―immuno
pc pc pc pc pc pc pc pc pc pc pc pc


surveillance‖ against cancer is a principal function of the immune system is controversial
pc pc pc pc pc pc pc pc pc pc pc pc


. Repair of injured tissues may be a secondary consequence of the immune responses and
pc pc pc pc pc pc pc pc pc pc pc pc pc pc


inflammation. Although the immune system has regulatory features that are needed to pr

event excessive inflammation, prevention of inflammatory diseases is not a primary funct

ion. The immune system can protect against microbial toxins, but it generally does not off

er protection against toxins of nonbiologic origin.

2. Which of the following infectious diseases was prevented by the first successfu
pc pc pc pc pc pc pc pc pc pc pc


l vaccination?
pc


a. Polio
b. Tuberculosis
c. Smallpox
d. Tetanus
e. Rubella
ANS: C p c


In 1798, Edward Jenner reported the first intentional successful vaccination, which was a

gainst smallpox in a boy, using material from the cowpox pustules of a milkmaid. In 1980,
pc pc pc pc pc pc pc pc pc pc pc pc pc pc pc


smallpox was reported to be eradicated worldwide by a vaccination program. Effective v

accines against tetanus toxin, rubella virus, and poliovirus were developed in the 20th ce

3. Which of the following is a unique property of the adaptive immune system?
pc pc pc pc pc pc pc pc pc pc pc pc


a. Highly diverse repertoire of specificities for antigens
pc pc pc pc pc pc


b. Self-nonself discrimination pc


c. Recognition of microbial structures by both cell-associated and soluble receptors
pc pc pc pc pc pc pc pc pc


d. Protection against viral infections pc pc pc


e. Responses that have the same kinetics and magnitude on repeated exposure to th

e same microbe pc pc




ANS: p c A

, Highly diverse repertoires of specificities for antigens are found only in T and B lympho
pc pc pc pc pc pc pc pc pc pc pc pc pc pc


cytes, which are the central cellular components of the adaptive immune system. Both th
pc pc pc pc pc pc pc pc pc pc pc pc pc


e innate and the adaptive immune systems use cell-
pc pc pc pc pc pc pc pc


associated and soluble receptors to recognize microbes, display some degree of self-
pc pc pc pc pc pc pc pc pc pc pc


nonself discrimination, and protect against viruses. On repeated exposure to the same mic

robe, the adaptive immune response becomes more rapid and of greater magnitude; this i

s the manifestation of memory.

f immunity?
pc


a. Innate and adaptive pc pc


b. Passive and active pc pc


c. Specific and nonspecific pc pc


d. Humoral and cell-mediated pc pc


e. Adult and neonatal pc pc




ANS: D p c


Both B and T lymphocytes are principal components of adaptive immunity. B lymphocyte
pc pc pc pc pc pc pc pc pc pc pc pc


s produce antibodies, which are the recognition and effector molecules of humoral immun

e responses to extracellular pathogens. T cells recognize and promote eradication of intrac

ellular pathogens in cell-

mediated immunity. Passive and active immunity both can be mediated by either B or T ly
pc pc pc pc pc pc pc pc pc pc pc pc pc pc pc


mphocytes. Specific immunity is another term for adaptive immunity. Both B and T lymph

d. Helper cells and antigen-presenting cells pc pc pc pc


e. Cytotoxic T lymphocytes and target cells pc pc pc pc pc




ANS: A p c


T cells can be classified into effector subsets that perform different effector functions. Mos
pc pc pc pc pc pc pc pc pc pc pc pc pc


t effector T cells are either helper T lymphocytes, which enhance the responses of other i
pc pc pc pc pc pc pc pc pc pc pc pc pc pc pc


mmune cells, including phagocytes and B cells, to infections, or cytotoxic T lymphocytes
pc pc pc pc pc pc pc pc pc pc pc pc


, which directly kill infected cells. Natural killer cells are not T lymphocytes.
pc pc pc pc pc pc pc pc pc pc pc pc


Antigen-presenting cells usually are not T cells. Memory T cells are not effector T cells. pc pc pc pc pc pc pc pc pc pc pc pc pc pc
