2. Functions of the Lymphatic and Immune Systems  Lymph Fluid and Vessels (lymph/o): Returns cellular waste and tissue fluid to the circulatory system  Lymph Nodes (lymph/o, adeno/o): Produces lymphocytes and filters harmful substances from lymph  Tonsils and Adnoids (tonsill/o, adenoid/o): Protects the entry into the respiratory system

5. Continued  Spleen (spleen/o): Filters foreign materials from the blood, stores red blood cells, and destroys worn out blood cells  Bone Marrow (myel/o): Produces blood cells  Lymphocytes (lymph/o, cyte): Plays an important role in immune reactions  Immune System (immun/o): Defends the body against harmful substances such as allergens, toxins, and malignant cells
