Across
- 5. Is the action of antibodies in neutralizing the effects of bacterial toxins on cells by binding to them.
- 10. Is the specific response of the body to invasion by pathogens.
- 11. Passive Immunity Is when antibodies made by the mother are passed to the baby via the placenta or breast milk.
- 12. Active Immunity Is when the body produces its own antibodies to an antigen acquired through vaccination/
- 14. Is the introduction of harmless forms of organisms by injection or mouth to produce artificial immunity.
Down
- 1. Are proteins that display antigens on the cell surface membrane.
- 2. Is the process of protecting people from infection by giving them passive or active artificial immunity.
- 3. Are lymphocytes made in the bone marrow which are found both in the lymph glands and free in the body once they are mature.
- 4. Is a process that makes a pathogen more easily recognized, engulfed and digested by pathogens.
- 6. Is the clumping of cells caused when antibodies bind to the antigens on pathogens.
- 7. Is a common, non-specific response to infection involving the release of histamines from mast cells and basophils causing the blood vessels to dilate, giving local heat, redness and swelling.
- 8. Are proteins or carbohydrates on surface of cells, toxins produced by bacterial and fungal pathogens, some whole viruses and bacteria that are recognized by white blood cells during the specific immune response to infection. They stimulate the production of an antibody.
- 9. Are lymphocytes made in the bone marrow that mature and become active in the thymus gland.
- 13. Is a cell displaying an antigen/MHC protein complex.
- 15. Is a glycoprotein that is produced in response to a specific antigen.
