Immune System Word Puzzle Across 2. Chemical messengers 5. Cells that circulate in lymph 6. chemical signals 7. Front line, first responding side of the immune system 8. A type of receptor used for recognizing pathogens in invertebrates 10. example of a first line defense immune cell, very phagocytic in nature. 12. Second line, specialized arm of the immune system 13. antibodies bound to antigens increase phagocytosis 14. Part of the innate immune system, most abundant Down 1. immune cells that circulate in hemolymph 3. pathogen cannot bind & therefore unable to infect host cell 4. infectious agent 9. Maintenance of a constant internal body environment. 11. dilates blood vessels, activates macrophages, etc. Answers Homeostasis Maintenance of a constant internal body environment.
