The respiratory system is made up of air passages that reach from the trachea to the lungs (bronchioles). These air passages are known as 'bronchi.' The left and right bronchi essentially divide, which creates the lobar, segmental, and sub-segmental bronchi. It is important to remember that air exchange does not happen in this portion of the lungs. The anatomical makeup of the bronchi system is simple. The left bronchi divides itself into two lobar bronchial branches, whereas the right divides into three lobar bronchial branches. The right bronchi are wider, shorter and take on a more vertical stance than the left. This allows for more complications to occur in the right bronchi. Bronchitis, asthma, lung infections and aspiration pneumonia often occur when there is some type of complication within the air passage that leads into the lungs.
Mesothelioma is one of the rarest forms of lung-related diseases, but it can very well end up affecting the bronchi area. Since this disease can be detrimental to a person's lungs, the air passage may also become infected. The doctor may set up testing that will allow him to see whether or not mesothelioma or any other complication may have ended up in the bronchial area.
