Across
- 3. DNA complexed to proteins, but not pure DNA
- 5. Site of T cell maturation
- 7. signaling B cells to participate in immune responses and potentially regulating immune response
- 10. blood cell makers
- 11. protecting the body's mucous membranes from microbial invasion and maintaining immune homeostasis.
- 12. Filter plasma and provides immune cells at major areas like armpits, groin, and neck
- 14. produced by lymphocytes, fibroblasts, and macrophages
- 15. network of connective tissue to support cells of the body
- 16. plays a crucial role in the initial immune response by activating the complement system and facilitating pathogen neutralization and clearance.
- 17. Product of T cells
- 19. stimulates release of histamines and has a role in allergic reactions
- 23. Survey tissue and find microbes, particulate, and injured or dead cells
- 26. defensive protein in blood plasma and body secretions
- 28. act as signals to the immune system, alerting it to the presence of pathogens and initiating an immune response.
- 29. binds to specific pathogens, such as viruses, bacteria, and toxins
- 30. Injection of immune serum
- 31. inflammations signals cause cells to migrate to the area
- 36. Immunity directed against a particular pathogen
- 38. special receptors that are able to identify and stick to foreign cells
- 39. All purpose phagocytic cells and a primary component of pus
- 40. deliver medication directly into a muscle, allowing for rapid absorption and are used for vaccines
- 41. engaging in phagocytosis and antigen presentation
- 42. Filters red blood cells and removes old red blood cells from circulation
Down
- 1. cell membranes
- 2. movement of white blood cells from the blood into tissue
- 4. Substance that prompts the generation of antibodies and triggers an immune response
- 6. made up of waterproof cells full of kerotin, constantly sloughed off
- 7. Key signs of redness, warmth, and swelling
- 8. Antibodies pass from mother to fetus via placenta
- 9. defense against microbial, immune regulation and communication between cells
- 13. mucous covering prevents bacteria from attaching
- 18. Vaccine; dead or attenuated pathogens
- 20. when re-exposed to the same pathogen, the body reacts so quickly that there is noticeable illness
- 21. enhances inflammation and phagocytosis to eat dead or weak antigens
- 22. The B cell is going to divide many types because there are thousands of the similar receptor shaped organisms
- 24. deliver a small volume of medication or substance directly into the dermis, the layer of skin beneath the surface
- 25. the layer of fat and connective tissue located just below the skin
- 27. Infection; contact with pathogen
- 32. plasma from clotted blood
- 33. Has some benefits than just negatives such as increasing metabolism, stimulates immune response, and speeds up other immune reactions
- 34. Serves as a way to mark cells as self so they are safe from destruction by our immune system
- 35. A type of white blood cell that plays a key role in fighting infections and repairing tissue damage
- 37. initiating and regulating inflammation, pathogen clearance, and immune cell recruitment.
