Lymph nodes are collections of lymph nodules that are held together by reticular tissue and are surrounded by an outer capsule. In the cortex of the lymph nodes, you will find several lymph nodules that contain T lymphocytes (outside dark) and B lymphocytes (center and light). Lymph enters the node through several afferent lymph vessels and travels between the lymph nodules through channels called trabeculae. It then pools in the medulla which has macrophages and B lymphocytes affixed to medullary cords. Lymph eventually leaves via an efferent lymph vessels.
