Across
  1. 2. Originating outside the body
  2. 4. A nonmotile connective tissue cell implanted along capillaries, especially in the lungs, skin, gastrointestinal tract, and gastrourinary tract.
  3. 6. Small molecules that are released during inflammation and specific immune reactions that allow communication between the cells of the immune system and facilitate surveillance, recognition, and attack.
  4. 7. An acquired resistance to an infectious agent due to prior contact with that agent.
  5. 9. A large antigen-processing cell characterized by long, branchlike extensions of the cell membrane.
  6. 12. It includes the spleen, thymus, lymph nodes, and GALT.
  7. 16. Chemical mediators that stimulate the movement of white blood cells.
  8. 17. Any trait or factor of a cell, virus, or molecule that makes it distinct and recognizable.
  9. 20. An enzyme found in sweat, tears, and saliva that breaks down bacterial peptidoglycan.
  10. 24. The primary infection fighting blood cells.
  11. 26. Natural human chemical that inhibits viral replication; used therapeutically to combat viral infections and cancer.
  12. 28. Blood cells involved in the transport of oxygen and carbon dioxide.
  13. 29. A large protein molecule evoked in response to an antigen that interacts specifically with that antigen.
  14. 30. A chemical substance produced by white blood cells that regulate development, inflammation, and immunity.
Down
  1. 1. Neutrophils, Esinophils, and Basophils.
  2. 3. mediators that affect the endothelial cells and smooth muscle cells of the blood vessels.
  3. 5. The viscous, opaque, usually yellowish matter formed by an inflammatory infection. It consists of serum exudate, tissue debris, leukocytes, and microorganisms.
  4. 8. The clear fluid expressed from clotted blood that contains dissolved nutrients, antibodies, and hormones but not cells or clotting factors.
  5. 10. The tendency of organisms to move in response to a chemical gradient (toward an attractant or to avoid adverse stimuli).
  6. 11. A cytoplasmic organelle containing lysozyme and other hydrolytic enzymes.
  7. 13. A white blood cell derived from a monocyte that leaves the circulation and enters the tissues. These cells are important in nonspecific phagocytosis and in regulating, stimulating, and cleaning up after immune responses.
  8. 14. A body formed in a phagocyte, consisting of a union between a vesicle containing the ingested particle (the phagosome) and a vacuole of hydrolytic enzymes (the lysosome).
  9. 15. The migration of intact blood cells between endothelial cells of a blood vessel such as a venule.
  10. 18. Formed elements in the blood that develop when megakaryocytes disintegrate. Platelets are involved in hemostasis and blood clotting.
  11. 19. A progeny of an activated B cell that actively produces and secretes antibodies.
  12. 21. The accumulation of excess fluid in cells, tissues, or serous cavities. Also called swelling.
  13. 22. Pertains to pus formers, especially the pyogenic cocci: pneumococci, streptococci, staphylococci, and neisseriae.
  14. 23. The second most common form of white blood cells.
  15. 25. Originating or produced within an organism or one of its parts.
  16. 27. This type of cell makes up 3% to 7% of circulating leukocytes.
