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