Tracto respiratorio superior

Los principales conductos y estructuras del tracto respiratorio superior son la nariz, la cavidad nasal, la boca, la garganta (faringe) y la laringe. El sistema respiratorio se encuentra recubierto por una membrana mucosa que segrega moco, el cual atrapa partículas pequeñas como polen o humo. Estructuras pilosas que se denominan cilios recubren la membrana mucosa y desplazan las partículas atrapadas en el moco fuera de la nariz. El aire que se inhala se humedece, se calienta y se limpia mediante el tejido que recubre la cavidad nasal.
