The role of the upper human airways in modifying incoming air and removing large particles has been well known for many years. Recently, it has become apparent that the upper airways, which include the nasal, oral, pharyngeal, laryngeal and upper tracheal passages, must be viewed as both a filter to protect the more distal airways and a possible site of toxicity. It is also possible that specific deposition sites of these airways may act as portals of entry for molecules which readily pass through the epithelium.
