Across
- 3. Intensifies the response of other immune fighters
- 4. Once activated will pour millions of antibodies into the blood stream
- 5. The immune system that develops throughout life and is antigen specific
- 13. Small white blood cells that recognize and control invaders
- 14. Leukocytes in the blood stream
- 15. Y-shaped proteins
- 16. The process of capturing and destruction of bacteria by phagocytes
- 17. The prostaglandin that initiates most of the alveolar bone destruction in periodontitis
- 18. Powerful biochemical mediators that increase the permeability and dilation of blood vessels to allow for increase movement of immune cells to the site of infection
- 19. White blood cells that capture microorganisms
- 21. When leukocytes push their way between the endothelial cells and enter the underlying connective tissue
Down
- 1. A biochemical mediator that signals the immune system to send more phagocytes to the site of infection
- 2. A group of enzymes that act together causing the breakdown connective tissue matrix in periodontitis
- 6. The immune system present at birth and is not antigen specific
- 7. The process whereby leukocytes engulf and digest microorganisms
- 8. Bactericidal and digestive enzymes
- 9. The attraction of leukocytes to the site of infection
- 10. Neutrophils that are the first responders that capture and destroy bacterial invaders
- 11. Antibodies are collectively known as:
- 12. Leukocytes in the tissues
