Across
- 2. Strong acid and enzymes within this organ digests microbes preventing infection
- 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
- 6. Monocytes develop into these phagocytic cells when they migrate into tissues.
- 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
- 9. A group of proteins that help attract phagocytic cells to invaders and help burst foreign cells
- 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
- 15. Also known as plasma cells, these lymphocytes make antibodies and so are vital for humoral immunity
- 16. A Y shaped protein produced by plasma cells that binds to an antigen
- 17. Microscopic single celled organism, some of which are beneficial and some of which cause disease
- 19. This type of immunity does not involve antibodies; Cells directly attack cancer cells, body cells infected by viruses, and foreign tissue/material
- 23. White blood cells
- 24. An infectious agent that can only replicate inside the cells of living organisms
- 25. This type of cell is part of the innate immune system and they kill cells without the need for antigen display
- 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.
Down
- 1. something capable of causing disease
- 3. Any structure that generates an antibody response; may be pathogenic or nonpathogenic
- 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.
- 7. Another term that means antibody
- 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
- 10. The term for the bacteria that live in the gastrointestinal and reproductive tracts that help prevent colonization of these areas by pathogenic bacteria
- 12. A term meaning cellular eating where a cell engulfs a particle such as another cell, bacteria, or foreign material.
- 13. When the body’s immune system attacks part of the body to which it should be tolerant, but isn’t
- 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
- 18. A particular type of T cell that is part of the adaptive immune system; they activate B cells, macrophages, and cytotoxic T cells
- 19. Small fingerlike projections help sweep invaders up the respiratory tract keeping them from invading the lungs
- 20. This type of T cell kills damaged cells, cancer cells, and/or virus infected cells that are displaying specific antigens
- 21. This class of lymphocytes are important in cell mediated immunity
- 22. This type of immunity involves antibodies binding with antigen; it is most effective for viruses that lie outside body cells, bacteria, and toxins.
