Aggregates of lymphoid tissue in various locations are called what?

Lymphatic nodules are small, unencapsulated clusters of lymphoid tissue found in mucosal surfaces and other scattered sites throughout the body. They gather immune cells (mainly B cells, with T cells nearby) to monitor for pathogens at areas like the gut and respiratory tract, and they can form germinal centers when actively responding to antigens. This makes them the general term for aggregates of lymphoid tissue located in various places. By contrast, lymph nodes are discrete, encapsulated filtering organs along lymphatic vessels, and the spleen is a specialized blood-filtering organ with distinct white and red pulp. Tonsils are specific lymphoid tissue at the pharyngeal entrance, but the broad, location-spanning term for these aggregations is lymphatic nodules.
