Across
- 1. Lymphocyte that directly kills antigens; called (CD8 +) T cell.
- 5. lymph nodes, spleen, and thymus gland. Tonsils and adenoids are other examples of lymphoid organs.
- 10. proteins(cytokines) that stimulate the growth of B and T lymphocytes
- 11. Substance that the body recognizes as foreign; evokes an immune response. Most antigens are proteins or protein fragments found on the surface of bacteria, viruses, or organ transplant tissue cells.
- 14. The ability to recognize and remember specific antigens and mount an attack on them. Humoral (B cells) and cell-mediated immunity (T cells) are examples.
- 16. antibody produced in a laboratory to attack antigens and to destroy cells; useful in immunotherapy
- 20. tiniest lymphatic vessels
- 24. Antibodies such as IgA, IgE, IgG, IgM, and IgD; secreted by plasma cells (mature B cells) in response to the presence of an antigen.
- 26. Lymphocyte that secretes antibodies. It matures from B lymphocytes.
- 27. Lymphocyte that aids B cells and stimulates T cells; (CD4 +) T cell.
- 28. Lymphocyte that matures into a plasma cell to secrete antibodies. The B refers to the bone marrow, which is where B cells most often originate.
- 29. use of immune cells, antibodies, or vaccines to treat or prevent disease
- 30. fluid in the spaces between cells. This fluid becomes lymph when it enters lymph capillaries.
- 31. thin, watery fluid found within lymphatic vessels and collected from tissues throughout the body. Latin lympha means clear spring water.
- 32. Mass of lymphatic tissue in the nasopharynx
- 33. Protection that an individual is born with to fight infection such as neutrophils, monocytes, macrophages, and NK cells. It is not antigen specific and does not elicit memory.
Down
- 2. Set of proteins in the blood that help antibodies kill their target.
- 3. Lymphatic vessel in the chest that drains lymph from the upper right part of the body. It empties lymph into a large vein in the neck.
- 4. Proteins secreted by cytotoxic T cells to aid in antigen destruction. Examples are interferons and interleukins.
- 6. Antigen-presenting cell. Shows T and B cells what to attack.
- 7. lymph nodes in the area between the lungs in the chest cavity
- 8. lymph nodes in the mesentery (intestinal region)
- 9. lymph nodes in the groin region
- 12. nodes Lymph nodes in the armpit (underarm)
- 13. large phagocyte found in lymph nodes and other tissues of the body
- 15. Lymph nodes near the aorta in the lumbar (waist) area of the body.
- 17. Body's ability to resist foreign organisms and toxins that damage tissues and organs. This includes natural immunity and adaptive immunity. The word immunity comes from Latin immunis, meaning exempt or protected from.
- 18. T cells (cytotoxic, helper and suppressor) respond to antigens and destroy them; a type of adaptive immunity.
- 19. B cells produce antibodies after exposure to specific antigens; type of adaptive immunity
- 20. collection of stationary solid lymphatic tissue along lymph vessels; contains cells (lymphocytes and macrophages) that fight infection.
- 21. Protein produced by B cells to destroy antigens
- 22. Lymph nodes in the neck region
- 23. carrier of lymph throughout the body; lymphatic vessels empty lymph into veins in the upper part of the chest
- 25. proteins (cytokines) secreted by T cells and other cells to aid and regulate the immune response
