  12. what is the lymphatic vessels function
    transport lymph
  13. what is the function of the lymph nodes
    cleanse the lymph

    more
  21. what do the epithelium function as in the lymphatic capillaries?
    one way valves
  22. in what parts of the body are lymphatic capillaries found?
    all parts of the body except nervous system, bone marrow, and tissues without blood vessels
  23. what is the largest lymphoid organ
    spleen
  24. what are the 3 groups of tonsils
