Some possible facts extracted from the text are:
1. Coughing is a reflex act aimed at cleaning the bronchi.
2. Coughing is always a sign of inflammation of the bronchial or tracheal mucosa, except in cases of laryngitis, which causes hoarseness or voice changes.
3. Coughing can be dry or wet, depending on the stage of the inflammatory process and the presence of mucus or pus.
4. Coughing is not caused by snot running down the throat, but by irritation of the cough receptors in the larynx, trachea and bronchi.
5. Coughing can lead to bronchial obstruction, which is a narrowing of the lumen of the bronchi due to spasm, swelling and secretion of mucus.
6. Bronchial obstruction can cause hypoxia, which is a lack of oxygen in the body, and trigger paroxysmal coughs, which are series of frequent coughs.
