WebAirway resistance is the resistance to the flow of air through the respiratory tract during inhalation and expiration. When air goes into the lungs, gas molecules meet resistance, as they hit the walls of the airways. Therefore, the diameter of the airways affects resistance. Resistance will increase if the diameter of the bronchioles decreases ...
