title: [Molecular and cellular mechanisms for protecting the respiratory organs from hazardous effects].
abstract: Knowledge of the mechanisms of the body's defense from poor exposures underlies the pathogenetical approach to examining the influence of environmental factors on human health. The respiratory organs are protected from poor exposures by several interrelated systems and mechanisms. The most important ones are an inspired air conditioning system, a respiratory tract self-cleansing system, a pulmonary non-specific bactericidal protection system, an alveolar respiratory surface self-cleansing system, a toxic substance metabolic and neutralizing system, and a specific immune defense system. Free radicals also play a great role in the physiology and pathology.
