  1. 2. Microbes that cause disease in a host organism.
  2. 6. Signaling proteins released by infected cells that inhibit viral replication.
  3. 9. Molecules shared by groups of pathogens that are recognized by pattern recognition receptors.
  4. 10. A chemical released during inflammation that increases blood vessel permeability.
  5. 13. A group of proteins in the blood that enhance immune responses and can cause pathogen lysis.
  6. 14. Physical, chemical, and biological barriers that block pathogen entry.
  7. 17. Immune cells that capture antigens and present them to T cells.
  8. 18. Innate immune responses that act inside the body once pathogens have entered.
  9. 19. Receptors on immune cells that recognize pathogen-associated molecular patterns.
  10. 20. Adaptive immune response involving B cells and antibodies in body fluids.

  1. 1. The process by which immune cells engulf and digest pathogens or debris.
  2. 3. An elevated body temperature that enhances immune function and inhibits pathogen growth.
  3. 4. White blood cells that lack visible granules in the cytoplasm.
  4. 5. Nonspecific, immediate immune response present from birth.
  5. 7. A life-threatening condition caused by severe systemic infection leading to widespread inflammation and organ failure.
  6. 8. Specific immune response that develops after exposure to a pathogen.
  7. 11. Granulocytes that combat parasites and participate in allergic reactions.
  8. 12. The most abundant white blood cells and the first responders to infection.
  9. 15. response Adaptive immune response involving T cells that target infected or abnormal cells.
  10. 16. A thick fluid composed of dead tissue, pathogens, and immune cells.
