title: [Cells of the respiratory system].
abstract: The authors review the different cellular types found in the airways, the alveoli and the pleura. They describe in detail the structure and the function of the bronchial mucociliary system and the immunological defense system of the airways. Also discussed, on an alveolar level, are the mechanisms of defense and filtering vis-à-vis air transported pollutants and the role of protease-antiprotease balance in the integrity of interstitial connective tissue.
