A 44-year-old woman is suffering from bacterial pneumonia. In the first stages of her illness she suffered from chest pain and had a high fever with diminished breath sounds
Currently she is feeling better and no longer has the chest pain or fever. She is in which stage of the immune response?
A) Recognition stage
B) Proliferation stage
C) Response stage
D) Effector stage
Ans: D
Feedback: Recognition of antigens as foreign, or nonself, by the immune system is the initiating event in any immune response. In the proliferation stage the circulating lymphocyte containing the antigenic message returns to the nearest lymph node. In the response stage, the differentiated lymphocytes function either in a humoral or a cellular capacity. In the effector stage, either the antibody of the humoral response or the cytotoxic (killer) T cell of the cellular response reaches and connects with the antigen on the surface of the foreign invader. The connection initiates a series of events that in most instances results in total destruction of the invading microbes or the complete neutralization of the toxin.
