A nursing student asks the instructor what indicates that there is but one immune response rather than separate humoral and cellular responses. What is the instructor's best response?
A) The movement of B cells in and out of lymph nodes
B) The interaction between T cells and B cells
C) The differentiation between types of T cells
D) There is nothing that indicates there is but one immune response
Ans: B
Feedback: T cells interact closely with B cells, indicating that humoral and cellular immune responses are not separate, unrelated processes, but rather branches of the immune response that interact. B cells do not move in and out of lymph nodes; the differentiation between types of T cells does not indicate a single immune system.
