Bronchitis is generally just a medical term to designate an inflammation of the bronchi (the plural of bronchus). The bronchi are the larger airway divisions that are from the split at the bottom of the trachea.
The following are two the types of bronchitis:
The bronchial tree
When you take a deep breath, air travels through the nose or mouth and then through the vocal cords, which are at the top of the trachea. This point is the beginning of the bronchial tree. From there, the air moves along the trachea and at the end of it splits into the two mainstem bronchi, the left and the right, that correspond with the left and right lung, respectively. Within the lung, the mainstem bronchi further divide into the secondary bronchi, bronchioles, and finally the respiratory bronchioles, which end in the alveolar ducts. Here the bronchial tree ends by delivering air to the alveoli, where the oxygen/carbon dioxide exchange takes pl ...
Primary Versions of Bronchitis
The following are two primary versions of bronchitis (inflammation/disease of the bronchi):
Acute bronchitis is usually a viral transient infection of the bronchi that is self-resolving and characterized by coughing that lasts from five days to three weeks. It is treated symptomatically, and antibiotics or steroids have little effect on the course of the illness.
Chronic bronchitis is not transient and is a type of chronic obstructive pulmonary disease (COPD).
What exactly is COPD?
According to the Global initiative for chronic Obstructive Lung Disease (G.O.L.D.) report of 2017, COPD is as follows:
“A common, preventable, and treatable disease that is characterized by persistent respiratory symptoms and airflow limitation that is due to airway and/or alveolar abnormalities usually caused by significant exposure to noxious particles or gases. The chronic airflow limitation that characterizes COPD is caused by a mixt ...
