Examine one bronchus, carefully dissecting away the lung tissue with curved scissors.
By the passage of bougies through a bronchoscope a stricture of the bronchus has been relieved in a similar manner.
bronchus bron·chus (brŏng'kəs)
n. pl. bron·chi (-kī', -kē')
Either of two main branches of the trachea, leading directly to the lungs.
