J21.0: Acute bronchiolitis due to respiratory syncytial virus
The small airways in your lungs are inflamed. Your inflammation is caused by respiratory syncytial viruses.
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. The smallest bronchial tubes are called bronchioles.
Your bronchioles have become inflamed. The bronchioles may become constricted due to the inflammation. As a result, breathing may become difficult. Typical symptoms are also coughing and a high temperature.
The inflammation in your bronchioles is caused by specific viruses. These viruses are respiratory syncytial viruses.
