Word! Airway Obstruction Say: air-way ub-struk-shun When
something keeps the air from moving in and out of the airways in
your lungs, it's called an airway obstruction. When someone has
asthma, the airways may become obstructed, or blocked, because
the airways are swollen, narrow, and clogged with thick mucus.
Obstructed airways can cause coughing, wheezing, and shortness
of breath.
