<prompt> All of the following are components of White pulp of spleen, except:Periaeriolar lymphoid sheathLymphatic follicleB lymphocytesVascular sinus  <response>: PAS OF WHITE PULP Periaeriolar lymphoid sheaths PALS are typically associated with the aeriole supply of the spleen; contain T lymphocytes. Lymph follicles with dividing B lymphocytes are located between PALS and marginal zone. IgM IgG2 are produced in this zone; these molecules play a role in opsonization of extracellular organisms, encapsulated bacteria in paicular. Marginal zone is located fuher away from the central aeriole in proximity to red pulp, it contains antigen presenting cells APCs. - Red pulp 90 of spleen have venous sinusoids and splenic cordsof Billroth
