How does increased airway resistance affect breathing?

• A. It makes breathing easier
• B. It increases airflow
• C. It hinders airflow
• D. It does not affect breathing

Answer: (C)

Increased airway resistance hinders airflow within the respiratory system. This is because resistance refers to the opposition against the flow of air through the airways. When the airways are narrowed or obstructed, whether due to factors like inflammation, mucus buildup, or bronchoconstriction, the pressure required to move air into and out of the lungs increases. As a result, the ability to inhale and exhale effectively is compromised. The lungs may not fill as readily due to the restricted pathway, making it more difficult to achieve adequate ventilation. This situation can lead to an increase in respiratory effort, as the body works harder to overcome the resistance and maintain sufficient gas exchange. In contrast, suggesting that increased airway resistance makes breathing easier or increases airflow overlooks the fundamental principles of respiratory mechanics. The notion that it does not affect breathing ignores the direct relationship between airway resistance and the efficiency of ventilation. Thus, recognizing the way increased resistance impedes airflow provides a clearer understanding of its impact on breathing.
