PHM 450 Exam 3 Questions With Complete Solutions_____ can cause damage to both primary and secondary
lymphoid organs in experimental animals. exposure can cause
decreased circulating immunoglobulins in the serum resulting in
diminished antibody response following exposure to antigens
Correct Answers PCB (polychlorinated biphenyls)
_____ cells are associated with antibody production and
secretion (when it comes into contact with an antigen it develops
into a mature form called a plasma cell) Correct Answers B
Cell
_____ cells are important in defending against viral infections-
they attack virus infected cells causing lysis (fast response,
active early in the immune response) Correct Answers NK
______ cells are commonly used to assess T cell dependent
response of B cells Correct Answers sheep RBCs
