Across
- 2. circulate in the blood and are attracted by signals from infected tissues
- 5. life threatening condition caused by overwhelming inflammatory response
- 6. found on innate immune cell
- 8. phagocytic cells, natural killer cells, antimicrobial proteins, inflammatory response
- 10. skin, mucous membranes, secretions
- 11. agents that have potential to cause disease
- 13. consists of about 30 proteins that are activated by substances on microbe surfaces
- 14. enables an animal to avoid or limit many infections
- 16. systemic inflammatory response triggered by substances released by macrophages
- 17. recognition of traits specific to particular pathogens using a vast array of receptors; slower response
- 18. discharge destructive enzymes; involved in allergic and anti-helminth responses
Down
- 1. recognition of traits shared by broad ranges of pathogens, using a small set of receptors; rapid response
- 3. antibodies defend against infection in body fluids
- 4. ingestion and breakdown of foreign substances including bacteria
- 7. stimulate development of adaptive immunity in cells that contact the environment
- 9. circulate within hemolymph and carry out phagocytosis
- 11. found on potential pathogens
- 12. provide innate defense, interfering with viruses and helping activate macrophages
- 15. found throughout the body; originate from monocytes
