Encased in a capsule, it also contains a medulla and a cortex.Germinal centers stain lighter and are less densely packed. General Function. The main function of the lymphoid system is to protect the body from pathogens (e.g., bacteria, virus, and parasites) and diseased cells (e.g., virus-infected or tumor cells).. A wealth of information is available regarding the mechanisms underlying lymphocyte recirculation, antigenic stimulation and proliferation and awaits the reader interested in learning more about the molecular control of lymphocyte activities in lymph nodes. Collagen fibers (blue) are restricted to the capsule, trabeculae and blood vessels. OTHER SETS BY THIS CREATOR. In order to confirm the presence of a malignant lymphoma, it is indispensable to perform a biopsy of a complete lymph node.
