Across
- 4. happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them
- 8. provided when a person is given antibodies to a disease rather than producing them through his or her own immune system
- 9. a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies.
- 10. A type of immune cell that is made in the bone marrow and is found in the blood and in lymph tissue.
- 11. Immunity that is naturally existing, Natural immunity does not require prior sensitization to an antigen
- 16. occurs when a virus has infected a cell, replicated new virus particles,
- 17. by which the body is given immunity to a disease by intentional exposure to small quantities of it.
- 19. A type of white blood cell
Down
- 1. a medicine (such as penicillin or its derivatives) that inhibits the growth of or destroys microorganisms.
- 2. A type of blood cell that is made in the bone marrow and found in the blood and lymph tissue.
- 3. a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
- 4. results when exposure to a disease organism triggers the immune system to produce antibodies to that disease
- 5. a type of cell within the body capable of engulfing and absorbing bacteria and other small cells and particles.
- 6. A complex network of cells, tissues, organs, and the substances they make that helps the body fight infections and other diseases
- 7. an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.
- 12. a method by which a virus can replicate its DNA using a host cell.
- 13. A type of white blood cell that makes antibodies.
- 14. treatment with a vaccine to produce immunity to a particular infectious disease or pathogen.
- 15. a large phagocytic cell found in stationary form in the tissues or as a mobile white blood cell, especially at sites of infection.
- 18. A cell that is part of the immune system and helps the body fight infections and other diseases
