TRUE or FALSE. Read each statement below carefully. Place a T on the line if you think a
statement is TRUE. Place an F on the line if you think the statement is FALSE.
T 1. Immunity is protection from illness or disease that is maintained by the body's
F 2. Natural passive immunity occurs when an antigen enters the body and the body
creates antibodies to fight off the antigen.
F 3. Natural active immunity occurs when antibodies are passed from a mother to the
fetus through the placenta or using colostrum or the breast milk.
T 4. Artificial active immunity occurs via a vaccination or immunization.
T 5. Artificial passive immunity occurs via a specific transfusion such as
immunoglobulins.
F 6. Transplant rejection is an abnormal response of the immune system that can
damage or destroy the transplanted organ.
T 7. Bone marrow is the source of all blood cells, including most immune system cells. It
produces immature, undifferentiated cells called stem cells.
T 8. Phagocytosis is the engulfing and destruction of invaders
T 9. Immunity is an adaptive internal protection that results in long- term resistance to
the effects of invading microorganisms.
T 10. Immunocompetence requires that inflammation, antibody mediated, and cell-
mediated responses all have optimal functioning.
