Across
- 2. Skin, epithelial membranes, and secretions
- 5. Pattern-Associated Molecular Patterns; found on potential pathogens
- 7. an enzyme present in the digestive system of invertebrates that breaks down cell walls protecting against ingested pathogens
- 9. provide innate defense, interfering with viruses and activating macrophages
- 11. about 30 proteins that are activated by substances on microbe surfaces
- 12. Immunity present in all animals and plants; a generalized defense that is active immediately upon infection
- 13. Agents that have potential to cause disease
- 14. the ingestion an breakdown of foreign substances including bacteria
Down
- 1. the circulatory fluid within invertebrates with open circulatory systems
- 3. Pattern Recognition Receptors; found on innate immune cells
- 4. the equivalent of WBC's inside invertebrates, they circulate within the hemolymph and carry out phagocytosis and release antimicrobial peptides
- 6. Immunity only present in vertebrates; a very organism specific, memory based immune defense
- 8. WBC's (granulocytes)that discharge destructive enzymes and are involved in allergic and anti-helminth responses
- 10. WBC's with segmented nuclei, they circulate in the blood and are attracted by signals from infected tissues; first responders to infection. Granulocytes.
- 11. a polysaccharide found in the exoskeleton of insects and cell wall of fungi
