description: "Tissue composed of specialized cells that are organized as a definite organ, situated along the course of lymphatic vessels, and consisting of an outer cortical and an inner medullary part. The lymph nodes are the main source of lymphocytes of the peripheral blood and serve as a defense mechanism by removing noxious agents, such as bacteria and toxins, and probably play a role in antibody production."
