J40-J47: Chronic lower respiratory diseases
J42: Unspecified chronic bronchitis
The air is breathed in through the mouth or nose. From there the air goes into the trachea via the larynx. At the end of the windpipe are two bronchial tubes (or bronchi) branching away from it. The bronchial tubes run into the lungs. What is more, the bronchial tubes divide into even smaller branches. The larynx, the trachea, the bronchia and the lungs are part of the lower airways.
Your bronchial tubes have been inflamed for a considerable time. Typical symptoms for a long-lasting inflammation of the bronchial tubes are regular coughing and phlegm. Phlegm is what we call mucus that is coughed up.
