Which factor is NOT associated with increased airway resistance?

Increased lung compliance refers to the ability of the lungs to expand and inflate easily. When lung compliance is high, it indicates that the lungs can stretch more easily and fill with air without requiring excessive effort. This characteristic actually helps to reduce airway resistance, as there is less effort needed for airflow through the conducting airways and into the alveoli.

Other factors listed, such as bronchial constriction, inflammation of lung tissue, and excessive mucus production, all contribute to increased airway resistance. Bronchial constriction narrows the airways, making it more difficult for air to flow through. Inflammation can lead to swelling and narrowing of the air passages, further obstructing airflow. Excessive mucus production can clog the airways, obstructing airflow and increasing resistance. Therefore, increased lung compliance stands out as the factor not associated with heightened airway resistance.
