- 3. These are formed in the bone marrow and release antibodies that fight bacterial infections.
- 6. Macrophages, Dendritic Cells, B Cells
- 7. Found within the lymph nodes, they are phagocytes that destroy bacteria, cancer cells, and other foreign matter in the lymphatic stream.
- 8. Proteins that lyse the cell wall of an antigen. They are part of the nonspecific defense mechanisms of the immune system and helps destroy pathogens by coating or puncturing them.
- 11. A bacterium, virus, or other microorganism that can cause disease.

- 2. Most common type of white blood cell and can leave the blood stream to attack bacteria.
- 4. A type of cell within the body capable of engulfing and absorbing bacteria and other small cells and particles.
- 5. Abnormally high body temperature.
- 9. A localized physical condition in which part of the body becomes reddened, swollen, hot, and often painful, especially as a reaction to injury or infection.
- 10. A toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.
- 12. Protein that is produced by lymphocytes and that attaches to a specific antigen and keeps them from harming the body.
- 16. Proteins (cytokines) secreted by T cells and other cells to aid and regulate the immune response.
