Across
  1. 1. oval lymphatic tissues on each side of the pharynx that filter air to protect the body from bacterial invasion; also called palatine
  2. 3. an enzyme found in saliva and sweat and tears that destroys the cell walls of certain
  3. 4. Produces blood cells, destroys damaged blood cells, stores blood cells
  4. 6. the quality of being unaffected by something
  5. 7. Found within the lymph nodes, they are phagocytes that destroy bacteria, cancer cells, and other foreign matter in the lymphatic stream.
  6. 8. amine formed from histidine that stimulates gastric secretions and dilates blood vessels
  7. 9. allow lysosomes to fuse with the vesicles that contain the ingested bacteria and viruses
  8. 11. chemicals released by T helper cells that stimulate B cells
  9. 13. Bean-shaped filters that cluster along the lymphatic vessels of the body. They function as a cleanser of lymph as wells as a site of T and B cell activation
  10. 18. Lymph nodes, spleen, and thymus gland
  11. 19. the two types of white blood cells that are part of the body's immune system: B lymphocytes form in the bone marrow and release antibodies that fight bacterial infections; T lymphocytes form in the thymus and other lymphatic tissue and attack cancer cells, viruses, and foreign substances.
  12. 20. Cells that develop from B cells and produce antibodies.
  13. 22. molecules that set the body's thermostat to a higher temperature. they are released by certain leukocytes
  14. 23. involved in nonspecific inflammatory response its a chemical that increase vascular permeability, which leads to edema and swelling, attract neutrophils
  15. 24. dead or weakened pathogens that are injected into the body to cause the production of antibodies that will prevent disease

  1. 2. large vessels with valves, which collect and carry lymph to lymph nodes
  2. 3. a thin coagulable fluid (similar to plasma but) containing white blood cells (lymphocytes) and chyle
  3. 5. Thick yellowish-white fluid that is formed in infected wounds. It is composed of dead and dying white blood cells (principally neutrophils), tissue debris, and dead microorganisms.
  4. 10. an organism that produces disease in a host organism disease being alteration of one or more metabolic functions in response to the presence of the organism
  5. 12. Gut-associated lymphoid tissue present in the wall of the small intestine, especially the ileum.
  6. 14. movement by a cell or organism in reaction to a chemical stimulus
  7. 15. a ductless glandular organ at the base of the neck that produces lymphocytes and aids in producing immunity
  8. 16. Antiviral proteins secreted by T cells
  9. 17. collects lymph from the left side of the head and neck, the upper left quadrant of the trunk, the left arm, and the entire lower portion of the trunk and both legs; empties into the left subclavian vein
  10. 21. foreign substances that trigger the attack of antibodies in the immune response.
