What primarily determines airway resistance in the respiratory passageways?
A)presence of surfactant
B)elasticity of the lung tissues
C)diameter of the conducting zone passageways
D)degree of alveolar surface tension

Question

Quizplus · Accepted Answer

Airway resistance in the respiratory passageways is primarily determined by the diameter of the conducting zone passageways. When the diameter of these passageways decreases, there is an increase in airway resistance. This can be caused by factors such as bronchoconstriction, inflammation, or the presence of foreign substances.
