Marginal Zone

The Marginal Zone (pronunciation: mahr-ji-nuhl zohn) is a region in the lymph node and spleen that is rich in B cells. It is an important part of the immune system, playing a crucial role in the body's defense against pathogens.

Etymology

The term "marginal zone" is derived from the Latin words "margo" meaning edge or border, and "zona" meaning belt or girdle. It refers to the location of this region at the edge or periphery of the lymph node or spleen.

Function

The Marginal Zone is primarily involved in the immune response to blood-borne antigens. It contains a high concentration of macrophages and dendritic cells, which are responsible for capturing and presenting antigens to B cells. This initiates the production of antibodies, a key component of the body's immune response.
