5 True/False Questions
Afferent Lymphatic Vessels → Vessels that bring lymph draining from connective tissue into a lymph node en route to the blood.
Hilum → mucosa-associated lymphatic tissue; composted of Peyer's patches, tonsils, appendix and lymphoid nodules in the bronchii; protects passages that open to exterior from the nerver-ending onslaughts of foreing matter entering them
Lymphadenopathy → chronic abnormal enlargement of the lymph nodes (usually associated with disease)
Lymphatic Capillaries → solid, spherical bodies consisting of tightly packed reticular elements and cells- often form parts of larger lymphoid organs (found isolated in distal small intestine and appendix)
Peyer's Patches → Lymphoid follicles situated along the wall of the small intestine that trap antigens from the gastrointestinal tract and provide sites where B and T cells can interact with antigen
