The adaptive and [[Innate Immune System|innate responses]] work together to destroy bacteria. The adaptive response ensures the [[Innate Immune System|innate response]] is carried out efficiently. There are two major branches of the adaptive immune response, humoral immunity and cell-mediated immunity.

==Extracellular Infection==

==Extracellular Infection==

The response to extracellular infection involves [[Complement|complement]] and phagocytosis; [[Lymphocytes#B Cells|B cell]] and T_H2 cell stimulation and the production of [[Immunoglobulin M|IgM]], which activates the classical cascade. T_H17 stimulation also enhances extravasation of neutrophils to the area to clear the pathogen. There is also class switching of [[Immunoglobulin M|IgM]] to [[Immunoglobulin G|IgG]], which is a good opsonin and targets bacterial Fcγ receptor expressed by [[Macrophages|macrophages]] and [[Neutrophils|neutrophils]].
