only one that actually cleanses lymph.
______2) where t cells mature so that they can actually defend us against pathogens when
activated in an immune response.
______3)... takes lymph from everywhere else to the heart via the subclavian vein
______4)...secrete antibodies into the blood; are made and mature in the red bone marrow.
______5) the protein-containing fluid that moves through lymphatic vessels.
______6)... clusters of lymphoid tissue in the ileum of the small intestine that monitor intestinal
bacteria populations and prevent the growth of pathogenic bacteria.
______7)...set of lymphoid tissues located in mucous membranes throughout the body.
______8)... contains a bunch of lymphoid tissue to prevent bacteria from breaching the
intestinal wall and generating \memory\ lymphocytes for establishing long - term immunity.
______9)...a ring of malt around the entrance of the pharynx that gathers and tries to remove
any pathogens from food or inhaled air before they can enter the gl tract or lungs

5. Lymph (A) is the protein - containing fluid.
6. Peyer’s patches (D) are in the ileum.
7. MALT (H) is in mucous membranes.
8. Appendix (C) has lymphoid tissue.
9. Tonsils (G) are a ring of MALT.
10. Right lymphatic duct (B) takes lymph from specific areas.
11. Lymphatic Vessels (I) collect and return fluid.
12. Spleen (J) cleanses blood.
13. T cells (K) attack and manage the immune system.
