==Function==

Peyer’s patches have a similar role to that of the avian [[Bursa of Fabricius - Anatomy & Physiology|bursa of Fabricius]] in maturing and differentiation immature B lymphocytes. Antigens are presented to the [[Lymphocytes#B cells|B lymphocytes]] in the follicle which causes the [[Lymphocytes#B cells|B cells]] to become committed to [[Immunoglobulin A - WikiBlood|IgA]] synthesis. In ruminants and pigs Peyer's patches in the [[Ileum - Anatomy & Physiology|ileum]] have a primary lympoid fuction while those in the [[Jejunum - Anatomy & Physiology|jejenum]] have a secondary lymphoid function.
