Immunology
1. Which disease damages the human immune system,
leaving the body open to certain infectious agents?
(1) flu
(3) chicken pox
(2) AIDS
(4) pneumonia
2. Bleeding from a small cut soon stops due to the release of
enzymes from
(1) platelets
(3) hemoglobin
(2) activated antibodies
(4) white blood cells
3. Which blood component is correctly paired with a process
in which it is directly involved?
(1) white blood cells–clotting
(2) platelets–oxygen transport
(3) lymphocytes–antibody production
(4) red blood cells–bacteria destruction
4. An individual who has had chicken pox rarely gets this
disease again. This situation is an example of
(1) biological control
(3) active immunity
(2) negative feedback
(4) passive immunity
5. A person who is given an injection containing only
antibodies would most likely develop
(1) allergies
(3) leukemia
(2) sickle-cell anemia
(4) passive immunity
6. Which statement does not identify a characteristic of
antibodies?
(1) They are produced by the body in response to the
presence of foreign substances.
(2) They may be produced in response to an antigen.
(3) They are nonspecific, acting against any foreign
substance in the body.
(4) They may be produced by white blood cells.
7. A part of the Hepatitis B virus is synthesized in the
laboratory. This viral particle can be identified by the
immune system as a foreign material but the viral particle
is not capable of causing disease. Immediately after this
viral particle is injected into a human it
(1) stimulates the production of enzymes that are able to
digest the Hepatitis B virus
(2) triggers the formation of antibodies that protect against
the Hepatitis B virus
(3) synthesizes specific hormones that provide immunity
against the Hepatitis B virus
(4) breaks down key receptor molecules so that the
Hepatitis B virus can enter body cells
8. Which activity would stimulate the human immune system
to provide protection against an invasion by a microbe?
(1) receiving antibiotic injections after surgery
(2) choosing a well-balanced diet and following it
throughout life
(3) being vaccinated against chicken pox
(4) receiving hormones contained in mother’s milk while
nursing
9. The use of a vaccine to stimulate the immune system to act
against a specific pathogen is valuable in maintaining
homeostasis because
(1) once the body produces chemicals to combat one type
of virus, it can more easily make antibiotics
(2) the body can digest the weakened microbes and use
them as food
(3) the body will be able to fight invasions by the same
type of microbe in the future
(4) the more the immune system is challenged, the better
it performs
10. Certain microbes, foreign tissues, and some cancerous cells
can cause immune responses in the human body because
all three contain
(1) antigens
(3) fats
(2) enzymes
(4) cytoplasm
11. A person with allergies may develop a rash and swollen
eyes when exposed to certain substances. These symptoms
are a reaction to
(1) histamines produced as a result of an immune reaction
(2) antigens produced as a result of passive immunity
(3) phagocytosis, resulting in the destruction of body cells
(4) an increase in the number of platelets
12. The release of histamines within the body is most closely
associated with
(1) rejection of a transplanted organ
(2) active immunity
(3) blood clotting
(4) an allergic reaction
13. Select the immune reaction, chosen from the list below,
that is best described by that statement.
Immune Reactions
(1) Passive immunity
(2) Allergy
(3) Rejection
Bronchial tubes constrict during an asthma attack.
(1) 1
(3) 3
(2) 2
14. Allergic reactions are most closely associated with
(1) the action of circulating hormones
(2) a low blood sugar level
(3) immune responses to usually harmless substances
(4) the shape of red blood cells

15. When people who are allergic to pollen come in contact
with pollen, their eyes begin to water and itch due to the
release of
(1) antigens from red blood cells
(2) enzymes from platelets
(3) histamines from body cells
(4) hormones from the pituitary gland
