Summary Introduction

To explain: The mechanisms that causes airway obstructions in asthma.

Concept introduction: Obstructive lung diseases refer to diseases involving obstruction of airways that worsen by expiration. In these diseases, emptying of the lungs is slowed; the body requires exertion of more force to exhale a given volume of air and use the accessory muscles for expiration. Asthma is the chronic inflammatory disorder of the bronchial mucosa, which leads to bronchial hyper-responsiveness, constriction of the airways, and variable airflow obstruction.
