Bronchial responsiveness and airway structure

Let us assume that airways are subjected to the same smooth muscle stimulation.

  • Airway structure and functionAirway narrowing is more pronounced in large airways due to their greater muscle mass.
  • Airway structure and functionAirway narrowing is more pronounced in small airways due to their relatively larger muscle mass.
  • Airway structure and functionAirway narrowing is most pronounced in small airways because they are more compliant.
  • Airway narrowing is most pronounced in large airways as their smooth muscles can shorten more. Airway structure and function
