Across
- 3. destroy cells by nonspecific and specific processes; uses perforins to form pores in enemy cell
- 4. perforates the plasma membrane of the target cell
- 7. causes many of the symptoms of allergies; causes inflammation in an attacked area; vasodilators
- 12. immune response that must be acquired either passively or actively
- 13. human leukocyte antigen complex; self recognition protein
- 14. clinical symptom of widespread inflammation; helps the body fight infection with elevated body temperature that increases phagocytosis; promotes break down of lysosomes to destroy infected cells
- 15. most common white blood cell; phagocytes
- 16. a third type of blood cell marker; D antigen
- 17. the ingestion of bacteria or other material by phagocytes
- 18. are secreted mainly by macrophages to regulate interactions between white blood and other cells; can update while blood cells on immune progress
- 19. peptides and proteins that serve as important signaling molecules and perform regulatory functions
Down
- 1. cells with long cytoplasmic extensions; develop from precursor cells in the bone marrow
- 2. responsible for cell-mediated immunity; attack body cells infected by invading pathogens
- 3. immune response that you are born with; innate; general protection
- 5. clumping of red blood cells which can block small blood vessels
- 6. mast cells that release histamine and other vasodilators
- 8. communicate that an enemy is preset so that cells can start protecting themselves
- 9. large phagocytes that develop from monocytes; nongranular white blood cell
- 10. the study of the internal defense systems of humans and other animals
- 11. responsible for antibody-mediated immunity; produce specific antibodies that bind to specific antigens
