The main bronchus (B. Principalis) is one of the main respiratory tracts that is located in the human chest. It starts from the larynx and passes through the lungs, connecting with other respiratory tracts. The main bronchus is one of the most important respiratory tracts, as it ensures the supply of oxygen to the lungs and the removal of carbon dioxide from them.
The main bronchus has several branches called bronchi. They are responsible for distributing air throughout the lungs and ensuring effective ventilation of the lungs. In addition, the bronchi are also involved in air filtration and removal of dust and other contaminants.
However, in some diseases, such as bronchitis or pneumonia, the main bronchus may be blocked or inflamed. This can lead to impaired lung function and poor breathing. Therefore, it is important to monitor the health of the bronchi and lungs to avoid possible problems.
In general, the main bronchus plays an important role in human breathing and health. Therefore, it is necessary to take care of its condition and maintain its normal operation.
