SPHU 1020 Test 1 With Complete
Solution
What is immunity? - ANSWER The resistance to disease, specifically infectious
disease
What is the immune system? - ANSWER The collection of cells, tissues, and
molecules that mediate resistance to infection
What is immunology? - ANSWER The study of the immune system and its
responses to invading pathogens
What are the two major functions of immunity? - ANSWER Preventing
infection/disease and eradicating established infections
What are the primary (central) lymphoid organs? - ANSWER Bone marrow
and thymus
What are the secondary (peripheral) lymphoid organs/tissue? - ANSWER
Lymph nodes, spleen, mucosal lymphoid tissue (tonsils, adenoids, Peyer's
patches)
What is the function of the spleen? - ANSWER To "filter" blood, thus filtering
blood-borne organisms
What are antigens? - ANSWER Foreign, non-self substances (also the
initiators and driving force for all adaptive immune response)
All blood cells originate in the ________ as _______ (name of cells) - ANSWER
Bone marrow; stem cells
, All cells of the immune system are derived from what two lineages? -
ANSWER Lymphoid lineage (B and T lymphocytes) and myeloid lineage
(phagocytes)
The immune system must be able to differentiate between material that is
_____ and _____. - ANSWER Self; nonself
True or False: The innate and adaptive immune systems sometimes interact
to perform some of their functions. - ANSWER True
What are the three other names for innate immunity? - ANSWER Native,
nonspecific, natural
What are the two other names for adaptive immunity? - ANSWER Specific,
acquired
What is innate immunity? - ANSWER The initial immediate defense against
invaders; it is nonspecific and less effective; includes first two lines of
defense
What is adaptive immunity? - ANSWER The later, more effective defense
against infections
What are the two types of adaptive immunity? - ANSWER Cell-mediated
immunity (CMI) and Humoral Immunity (Antibody-mediated Immunity)
What is the first line of defense? - ANSWER Epithelial barriers, specialized
cells and substances present in epithelia (they block entry of microbes)
What is the second line of defense? - ANSWER Phagocytes, natural killer
cells; specifically recognize and react against microbes but not against
non-infectious foreign substances
