MATERIALS AND METHODS PASSAGES protect the lower airways by warmg, humidifyg, and cleang spired air (8). The baboon was selected because it is suitable for both procedures, and this species has been used fairly extensively for respiratory physiology studies. The results were compared with those obtaed by usg water flow with a marker dye combed with analytic cephotography. velocity profiles were determed a wd tunnel usg a thermistor probe technique. The present study was conducted to determe whether the flow of water through a plastic mold gave meangful dication of the flow of air through the same mold. However, the validity of this model has yet to be determed for complex tubes, such as the nose.
Rodents, which are used extensively for halation toxicology studies. Journal of Applied Physiology The American Physiological Society The distribution of these lesions is probably attributable, at least part, to delivery of haled toxic materials to specific s of the nose as a consequence of patterns. Exposure of the nose to toxic particulate matter (14) and irritant gases (1) results lesions specific s of the mucosa. Furthermore, the nose represents a potential target site durg exposure of human (8) and animals (1) to haled air pollutants.
