Down
- 1. type of white blood cell that is produced and matures within the bone marrow, produce antibodies
- 2. resistance to disease that is acquired from the introduction of antibodies from another individual rather than an individual's own immune system (e.g. across the placenta/mother's milk)
- 3. the response of the immune system to an allergen
- 6. mechanism by which cells engulf particles to form a vesicle or a vacuole
- 8. a substance produced by living organisms that can destroy or inhibit the growth of microorganisms
- 9. a protein produced by lymphocytes in response to the presence of the appropriate antigen
- 11. a normally harmless substance that causes the immune system to produce an immune response
- 14. cell type that secretes antibodies into the blood plasma
- 15. the introduction of a vaccine containing appropriate disease antigens into the body, by injection or mouth, in order to induce artificial immunity
