Across
- 4. Type II pneumocytes (great ........ alveolar cells) responsible for the production of surfactant and the replacement of damaged Type I pneumocytes, through the process of differentiation and replication.
- 7. An antimicrobial agent used to treat bacterial infections.
- 9. A pathogen that is normally a commensal, but can cause disease when the host’s resistance is low.
- 11. Causative pathogen of most upper respiratory tract infections characterized as the "common cold".
- 12. An inflammatory condition of the lung affecting predominantly the alveoli and usually caused by a pathogen.
Down
- 1. Type I pneumocytes (simple …….. alveolar cells) incapable of replication, which form the alveolar epithelium and are particularly susceptible to bacterial toxins.
- 2. Inflammation of the mucosal membranes of the bronchioles.
- 3. A white blood cell which engulfs extracellular pathogens.
- 5. Specialized tissue specific monocyte involved in phagocytosis.
- 6. A protein found in the respiratory tract which forms an essential part of the innate antimicrobial defense system.
- 8. An RNA virus which causes seasonal outbreaks of respiratory infection.
- 10. Enzymes that damage bacterial cells walls.
