title: [Respiratory defence mechanisms. Particular circumstances in healthy and sick children].
abstract: Foreign particle clearance and sterilization of the tracheobronchoalveolar apparatus rely upon two main defense mechanisms: the mucociliary escalator and the bronchoalveolar lymphoid tissue. The physiological and pathophysiological particularities of these two systems in children, and their therapeutic implications, are described.
