The bronchi are tubes that result from the bifurcation of the trachea. Each conduit or bronchus is connected to a lung: the left and the right.
The bronchi have complete cartilaginous rings, and the lungs divide in a branching way until they become small conduits (the bronchioles). The function of the bronchioles is to conduct air, but when they reach their final structure (usually they are like the branches of trees) they form alveoli, which allow the gas exchange between the inspired air and the organism’s blood.
In this way, air enters through the trachea and reaches the lungs through the bronchi
The right bronchus is formed by three branches or lobular bronchi: the superior, the middle and the inferior. The left bronchus has two lobes.
The bronchi are therefore a lower part of our body’s respiratory tract.
Diseases related to the bronchi
The most common condition is bronchitis, an inflammation that lines the bronchi and causes difficulty in the entry and exit of air from the lungs. In some cases, bronchitis can become chronic , and it is common to take drugs to reduce inflammation, also known as bronchodilators. Chronic bronchitis is known as EPOC ( acronym meaning disease chronic obstructive pulmonary) and is usually caused by smoking. Although bronchitis is a well-known disease, there are others that also affect this anatomical structure: asthma, bronchopneumonia, bronchial fistula, etc.
Some respiratory diseases are directly related to atmospheric contamination
The lungs and bronchi are the anatomical structure that allows us to breathe normally. An alteration in the respiratory process causes a decrease in our physical capacity and this type of limitation must be treated through pulmonology, or even through a better known discipline : bronchology.
There are medical techniques and instruments that have a direct relationship with the bronchi: spirometry, which is a test that measures lung capacity and bronchial function, while the bronchoscope is a device introduced into the trachea to observe the airways.
