==Humoral==

==Humoral==

Humoral immunity includes [[Complement|Complement]] activation of the classical pathway. It results in the production of [[Immunoglobulin M|IgM]] and [[Immunoglobulin G|IgG]] and makes the complement system more efficient.

==Extracellular Infection==

==Extracellular Infection==

The response to extracellular infection involves [[Complement|Complement]] and phagocytosis; [[Lymphocytes#B Cells|B cell]] and T helper type II cell stimulation and the production of [[Immunoglobulin M|IgM]], which activates the classical cascade. 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]].
