oFirst, it functions strictly in maturation of T lymphocyte precursors and thus is the only lymphoid organ thatdoes not directly fight antigens.oSecond, the stroma of the thymus consists of epithelial cells rather than reticular fibers. These epithelial cellsprovide the physical and chemical environment in which T lymphocytes can become immunocompetent.Tonsils are the simplest lymphoid organs. They form a ring of lymphatic tissue around the entrance to the pharynx(throat), where they appear as swellings of the mucosa. The tonsils gather and remove many of the pathogens enteringthe pharynx in food or in inhaled air.oPalatine Tonsils are located on either side at the posterior end of the oral cavity. These are the largest of thetonsils and the ones most often infected.oLingual Tonsil - lumpy collection of lymphoid follicles at the base of the tongue.oPharyngeal Tonsil (referred to as the adenoids if enlarged) is in the posterior wall of the nasopharynx.
