Across
  1. 4. is a protein found in our blood that transports oxygen to our tissues
  2. 6. identify general molecular patterns found on groups of pathogens, rather than targeting specific individual pathogens, which helps in recognizing a broad range of invaders despite mutations
  3. 8. present intracellular peptides to CD8+ to help destroy infected cells
  4. 12. are pre-produced and stored inside neutrophils; they move to the cell surface quickly in response to infection
  5. 14. cells detect antigens shown by MHC class II molecules on antigen-presenting cells and release cytokines to accelerate the immune response
  6. 15. include neutrophils, lymphocytes, monocytes, eosinophils, basophils and are found in the “buffy coat” of blood.
  7. 16. Dense layer of blood
  8. 18. The _______ immune system develops targeted responses to specific pathogens through the activation of B cells and T cells.
Down
  1. 1. are messengers of the immune system that send alerts to other immune cells to prepare for battle against invaders.
  2. 2. are considered “warning proteins” that interfere with the reproduction of viruses by producing antiviral proteins
  3. 3. The _____ activation pathway activates the complement system by binding specifically to carbohydrates, such as mannose, on the surface of pathogens.
  4. 5. are most abundant innate immune cells that store powerful chemicals inside of the cell and release in the presence of pathogens.
  5. 7. pathway relies on spontaneous reactions involving C3, leading to the destruction of pathogens
  6. 9. The complement system produces proteins in the ______ to destroy foreign pathogens and communicate with other immune cells
  7. 10. cells reside in tissues and act as messenger "bridge" cells that present antigens to adaptive immune cells in the lymph nodes.
  8. 11. on gram-negative bacteria binds to receptors on immune cells triggering the release of cytokines and activates the immune response.
  9. 13. is an the most abundant antibody found in human blood and is produced by plasma B cells
  10. 17. immune system is the body’s first line of defense that responds quickly to pathogens without prior exposure.
