How does bronchitis cause?

Generally, the air we breathe is purified through the nasal cavity. Nasal air filtration, heating and wetting, in this process, the role of nasal hair is great. So it's easy to break the defense system by digging your nose often. The epithelial cells of trachea and bronchus mucosa are covered with cilia, which can secrete a large amount of mucus, so they can absorb particles with smaller diameter. Meanwhile, the cilia constantly swing upward, pushing the mucus containing foreign bodies to the throat, and finally coughing up the body. This is the disgusting sputum.

Smoking increases the excitability of parasympathetic nerve (vagus nerve) and leads to bronchospasm; The mucus secretion of airway epithelial cells increased, but the cilia movement was inhibited, so that a lot of rubbish accumulated in the trachea; Bronchial mucosa congestion, edema, mucus accumulation, alveolar phagocytic function of phagocytes phagocytic bacteria and viruses weakened, in general, smoking weakened all of the above lines of defense.

Infection is an important factor in the occurrence and development of chronic bronchitis, mainly virus and bacterial infection. Although infection is closely related to the occurrence and development of chronic bronchitis, there is not enough evidence to prove that it is the first cause. It is only considered to be an important factor of secondary infection and aggravating the development of chronic bronchitis.

Bronchitis patients should not only be treated in the onset period, strengthen the control of the disease, but also actively prevent when the disease is not serious. 2. Using cold water when washing face can prevent bronchitis. 3. Wearing a mask in winter can not only filter dust and other large particles of pollutants, but also heat the cold air and keep the face warm.
