==Extracellular Infection==
The response to extracellular infection involves [[Complement|complement]] and phagocytosis; [[Lymphocytes#B Cells|B cell]] and T<sub>H</sub>2 cell stimulation and the production of [[Immunoglobulin M|IgM]], which activates the classical cascade. T<sub>H</sub>17 stimulation also enhances extravasation of [[Neutrophils|neutrophils]]

T<sub>H</sub>17 stimulation also enhances extravasation of [[Neutrophils|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]].
