Across
- 2. Any substance that causes the body to make an immune response against that substance
- 4. defense that immune cells that target specific antigens
- 6. an infectious microbe consisting of a segment of nucleic acid
- 8. defense that is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals
- 13. acquired from exposure to the disease organism through infection with the actual disease
- 15. originate in the bone marrow
- 16. A type of immune cell that can surround and kill microorganisms, ingest foreign material, and remove dead cells
- 17. a protein component of the immune system that circulates in the blood, recognizes foreign substances like bacteria and viruses, and neutralizes them
- 18. key player of the adaptive immune response that is responsible for humoral immunity in mammals
- 19. A type of immunity that occurs when a person is given antibodies rather than making them through his or her own immune system
Down
- 1. results when exposure to a disease organism triggers the immune system to produce antibodies to that disease
- 2. a mean by which the body is given immunity to a disease by intentional exposure to small quantities of it
- 3. part of the immune system and develop from stem cells in the bone marrow
- 5. responds to antigens by producing cells that directly attack the pathogen
- 7. disrupt essential processes or structures in the bacterial cell
- 9. defense that is he innate immune system
- 10. help the body fight infection and other diseases
- 11. macrophages have roles in almost every aspect of an organism's biology ranging from development, homeostasis, to repair through to immune responses to pathogens
- 12. produce antibodies that are used to attack invading bacteria, viruses, and toxins.
- 14. Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body
