What tissue processes B cells before they are sent to peripheral lymphoid tissue?

Explanation:
B cells are educated in gut-associated lymphoid tissue before they diversify and populate other lymphoid sites. GALT is a major mucosal immune hub, rich in B cells, where they encounter gut antigens, undergo activation, and often switch to IgA production. This prepares them for effective defense at mucosal surfaces and helps seed IgA-producing cells into peripheral lymphoid tissues. The other terms aren’t standard mucosal immune sites used for this B cell processing, so GALT best fits the idea of B cells being prepared for distribution to peripheral lymphoid tissues.
