This figure depicts asthma airways.  The middle airway describes a normally open airway that allows easy passage of respiratory gases.  On the reader’s right is an inflammatory airway with swelling and secretions.  On the reader’s left, bronchospasm is included in the inflammatory pattern - further constricting the airflow.

This video depicts an asthma airway undergoing an inflammatory reaction that includes swelling, secretions, and bronchoconstriction.  The end result is airway obstruction, air trapping and increased work of breathing.
