5. system consists of about 30 proteins that are activated by substances on microbe surfaces
6. cells release chemicals directly leading to cell death, inhibiting the spread of virally infected, or cancerous cells
8. immunity recognition of traits specific to particular pathogens, using a vast array of receptors
10. circulate in the blood and are attracted by signals from infected tissues
12. signals protein molecules that modulate the immune response and promote blood flow to the site of injury or infection
13. a fluid rich in white blood cells, dead pathogens, and cell debris from damaged tissues
14. is the ingestion and breakdown of foreign substances including bacteria
15. circulate within hemolymph and carry out phagocytosis; NO BLOOD

1. is a systemic inflammatory response triggered by substances released by macrophages
2. immunity recognition of traits shared by broad ranges of pathogens, using a small set of receptors
3. provide innate defense, interfering with viruses and helping activate macrophages
4. triggers blood vessels to dilate and become more permeable to tissues
7. cells stimulate development of adaptive immunity in cells that contact the environment (such as skin).
9. discharge destructive enzymes
11. shock is a life-threatening condition caused by an overwhelming inflammatory response
