B lymphocytes, commonly called B cells are mainly found within specialized lymphoid organs, however B lymphocytes also circulate in the peripheral blood, thus allowing movement into many different body tissues. Constant movement of B lymphocytes allows immune response/defence to be readily available. Proliferation, where B lymphocytes convert into plasma cells, occurs when a specific B cell antigen stimulates the B lymphocyte, these plasma cells then secrete specific proteins: immunoglobulins. B cells, along with plasma cells and antigens form the basis of humoral response within blood and body fluids.
