ANSWERS
adaptive and innate immune systems - Answers - what are the two major types of
immune system?
adaptive immune system - Answers - this type of immune system has a memory and
acquires knowledge of diseases encountered during life
adaptive immune system - Answers - which type of immune system involves T and B
cells?
innate immune system - Answers - this type of immune system is nonspecific and the
first line of defense for the body
innate immune system - Answers - which type of immune system involves phagocytic
and antigen presenting cells?
specific binding to antigen
participation in effector reactions - Answers - what are the two major functions of
antibodies?
IgG, IgM, IgA, IgE, IgD - Answers - what are the major classes of human
immunoglobulins? (5)
cytokines - Answers - peptide mediators released by stimulated cells is called...
mediators of natural immunity
regulators of lymphocyte activation growth/differentiation
activators of inflammatory cells
stimulators of immature leukocyte growth/differentiation - Answers - what are the major
functions of cytokines?

acts directly to neutralize invaders

cytokines or cell-cell interactions?
T cytotoxic cells - Answers - which type of T cell kills infected cells via lysis?
, T regulatory cells - Answers - which type of T cell maintains self tolerance (limits
autoimmunity)?

of the lymphatic system?
a lot of antigen presentation occurs - Answers - what happens in the lymph nodes?
collects antigen from blood
disposal of RBC - Answers - what happens in the spleen?
