SLIDE 1.2.3 With asthma, what we see is the tip of the iceberg, the symptoms. At the base of the iceberg is the airway inflammation. This inflammation underlies the bronchial hyperresponsiveness of asthma. Airflow obstruction results from bronchoconstriction, bronchial edema, mucus hypersecretion and inflammatory cell recruitment including eosinophils, a key inflammatory cell. The culmination of the inflammatory process is the tip of the iceberg, the symptoms.
