Across
  1. 5. this signals protein molecules that modulate the immune response and promote blood flow to the site of injury or infection
  2. 6. are found throughout the body; originate from monocytes
  3. 7. (two words) stimulate development of adaptive immunity in cells that contact the environment (skin); agranulocyte; have long arms for capturing and presenting antigens to the immune system
  4. 10. the ingestion and breakdown of foreign substances, including bacteria
  5. 11. agents that cause disease, infect wide variety of animals, including humans (some bacteria and viruses)
  6. 12. triggers blood vessels to dilate and become more permeable to tissues
  7. 14. consists of 30 proteins that are activated by substances on microbe surfaces
  8. 15. a type of leukocyte/white blood cell
Down
  1. 1. circulates in the blood and are attracted by signals from infected tissues; first responders to the infection
  2. 2. circulate within hemolymph and carry out phagocytosis (there is no blood); also release antimicrobial peptides that disrupt the plasma membrane of fungi and bacteria
  3. 3. discharge destructive enzymes; granulocyte; involved in allergic and anti-helminth responses
  4. 4. (two words) a life-threatening condition caused by an overwhelming inflammatory response (40% average mortality rate)
  5. 8. traps and allows the removal of microbes
  6. 9. provide innate defense, interfering with viruses and helping activate macrophages
  7. 13. a systematic inflammatory response triggered by substances released by macrophages
