Which of the following would be expected to increase the measured airway resistance?

Question

Quizplus · Accepted Answer

Stimulation of parasympathetic nerves to the lungs causes bronchoconstriction, which increases airway resistance. Low lung volumes can also lead to airway closure and increased airway resistance. Release of histamine by mast cells can cause bronchoconstriction, increased mucus production, and swelling of the airway, all of which increase airway resistance. Forced expirations can increase airway resistance by generating high airway pressures that compress the airways. Therefore, all of the above factors can increase measured airway resistance.
