Across
  1. 2. Strong acid and enzymes within this organ digests microbes preventing infection
  2. 4. This term means a lack of immune response to a particular antigen; this is helpful in preventing the immune system from attacking the body
  3. 6. Monocytes develop into these phagocytic cells when they migrate into tissues.
  4. 8. This nonspecific barrier is covered with oily and acidic secretions from sweat and oil glands as well as enzymes that help to defend against invaders
  5. 9. A group of proteins that help attract phagocytic cells to invaders and help burst foreign cells
  6. 11. A type of B cell that is responsible for the faster antibody response that occurs when an organism has already been exposed to the antigen and has previously developed antibodies to it
  7. 15. Also known as plasma cells, these lymphocytes make antibodies and so are vital for humoral immunity
  8. 16. A Y shaped protein produced by plasma cells that binds to an antigen
  9. 17. Microscopic single celled organism, some of which are beneficial and some of which cause disease
  10. 19. This type of immunity does not involve antibodies; Cells directly attack cancer cells, body cells infected by viruses, and foreign tissue/material
  11. 23. White blood cells
  12. 24. An infectious agent that can only replicate inside the cells of living organisms
  13. 25. This type of cell is part of the innate immune system and they kill cells without the need for antigen display
  14. 26. This type of immunity involves the recognition and processing of an antigen such that a specific and targeted attack is made by the immune system which includes a memory response which will make future responses to that specific antigen faster and more efficient.

  1. 1. something capable of causing disease
  2. 3. Any structure that generates an antibody response; may be pathogenic or nonpathogenic
  3. 5. Redness, heat, pain, swelling and loss of function are hallmarks of this protective response to injury designed to help remove the inciting cause and speed healing.
  4. 7. Another term that means antibody
  5. 8. This type of T cell, also known as a Regulatory T Cell, serves to decrease the immune response thus helping to prevent autoimmune disease
  6. 10. The term for the bacteria that live in the gastrointestinal and reproductive tracts that help prevent colonization of these areas by pathogenic bacteria
  7. 12. A term meaning cellular eating where a cell engulfs a particle such as another cell, bacteria, or foreign material.
  8. 13. When the body’s immune system attacks part of the body to which it should be tolerant, but isn’t
  9. 14. Chemical properties of the antigen activate this type of immunity which consists of nonspecific physical barriers, proteins in the blood, and certain immune system cells
  10. 18. A particular type of T cell that is part of the adaptive immune system; they activate B cells, macrophages, and cytotoxic T cells
  11. 19. Small fingerlike projections help sweep invaders up the respiratory tract keeping them from invading the lungs
  12. 20. This type of T cell kills damaged cells, cancer cells, and/or virus infected cells that are displaying specific antigens
  13. 21. This class of lymphocytes are important in cell mediated immunity
  14. 22. This type of immunity involves antibodies binding with antigen; it is most effective for viruses that lie outside body cells, bacteria, and toxins.
