The principal pathologic finding in the diagnosis of bronchiectasis is chronic dilation of the airways (bronchi and bronchioles).
<h3>What are the airways?</h3>
The airways are the structures that the body uses to interchange gases with the surrounding environment.
The bronchi are major airways, whereas bronchioles are the smallest structures that generate tiny air sacs known as alveoli.
Moreover, bronchiectasis symptoms include, among others, chest pain, wheezing and shortness of breath.
