Bronchiectasis

Bronchiectasis (brong-ke-EK-ta-sis) is a condition in which damage to the airways causes them to widen and become flabby and scarred. [web.archive.org]

Because bronchiectasis creates an abnormal widening of the airways, extra mucus tends to form and pool in parts of the widened airways. [who.int]
