Answer:
Airways diameter can influence the airflow resistance.
Explanation:
Airflow resistance follows the same principle followed by the airway resistance. This is the resistance offered during the pulmonary blood flow. 
Airways diameter affects the airflow resistance. If the diameter of airway is increased, the airflow resistance decreases and air can flow easily in the body. The decrease in the airway diameter (dilution) increases the airflow resistance of the blood artery.
