Explanation / Answer

Question: What is structural difference between a lymphatic organ and a lymphatic nodule?

Answer: Lymphatic organs are organs with discrete structure that consist of lymphatic nodules and diffuse lymphatic tissue, that are isolated from surrounding tissues by a well-defined capsule of dense connective tissue. These structures include the lymph nodes, spleen and thymus. Lymphatic nodules are discrete, concentrated regions of lymphoid tissue that lack a connective tissue capsule. They are found in the walls of the gastrointestinal, respiratory, reproductive, and urinary tracts.
