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