 Bronchus / Bronchi / Bronchioles
When a person takes in a breath of air, the air travels through the nose or mouth, into the larynx, then into the trachea, which is the main passageway into the lungs.
As the airway passages make their way out to the lung tissue, the passages become smaller and are referred to as bronchioles.
Eventually the bronchioles terminate into small collections of air sacs known as alveoli, which is where the actual exchange of CO and Oxygen occur.

 Declines in Lung Cancer Rates --- California, 1988--1997
Annual lung and bronchus cancer (International Classification of Diseases, for Oncology, codes C340--C349) incidence rates per 100,000 population during 1988--1997 were reported among men, women, and both sexes combined for California and the eight SEER regions combined (Table 1).
Among men, lung and bronchus cancer incidence rates declined significantly during 1988--1997 in data from the CCR and the SEER regions; however, the decline was greater in CCR (EAPC=--2.9%; p<0.01) compared with non-California SEER regions (EAPC=--1.8%; p<0.01).
The difference in the rate of decline in lung and bronchus cancer incidence rates between California and other U.S. regions may be related, in part, to the significant declines in smoking rates as a result of California tobacco control initiatives.

Although thoracic complication of odontogenic infection is rarely seen, early recognition of this complication is of vital importance in view of the high morbidity and mortality rate.[1,2] An infection in the oropharynx can descend through the various layers of the deep cervical fascia and cause a purulent mediastinitis.
Bronchoscopy confirmed a perforation of 4 to 5 mm in diameter in the anteromedial wall of the left main bronchus at a distance of approximately 2 cm from the carina tracheae (Fig 2).
For 29 of these patients, the mediastinitis was odontogenic.[1-4] A fistula to a bronchus as a complication of mediastinitis has not yet been reported, to our knowledge.

On both sides, the bronchus is posterior and the pulmonary vein(s) are anterior and inferior.
This "conducting" bronchus branches about 15 times, the result of which is small "terminal" bronchioles.
The superior segmental bronchus branches posteriorly off of the intermediate bronchus or the inferior lobe bronchus, so it is the most likely segmental bronchus to receive those foreign bodies that enter the right bronchus.

A 68-year-old man underwent left pneumonectomy via a standard posterolateral thoracotomy for squamous cell carcinoma of the upper lobe of the left lung which was invading the distal main bronchus.
Furthermore, it is conceivable that in some patients rigid fibrosis and tight adhesion of the inflammatory pleural membrane to the lower trachea and carina may render use of a stapling device difficult or impossible.
We conclude that closure of a main bronchus fistula using VAMS in patients with a short bronchial stump is a promising technique that deserves further development.

Since the left main bronchus has a longer mediastinal course than the right, injury to the left main bronchus is more likely to cause a pneumomediastinum, while injury to the right main bronchus is more likely to cause a pneumothorax.
In an uncomplicated pneumothorax, the bronchus remains fixed at the hilum, and the peripheral lung retracts from the parietal pleura toward the hilum.
With complete laceration of the main bronchus, the bronchus may become partially or completely detached, allowing the lung to fall into a dependent lateral position and producing the fallen lung sign.
