5 True/False questions
Spleen → 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
Diffuse Lymphatic Tissue → Vessels leaving the lymph node
Lymphangitis → inflammation of a lymph vessel
Tubal Tonsils → Collection of lymphoid follicles on the base, posterior, or pharyngeal portion of the dorsum of the tongue.
Lymphatic Capillaries → These are the vessels where lymph first enters the lymphatics. These are made up of loose endothelial cells that form flaplike minivalves held outward by collagen filaments which give them extreme permeability.
