Answer:
Ventilation may increase to compensate for the reduction in gas exchange.
Explanation:
The conducting zone is part of the respiratory system. It includes the organs and structures not directly involved in gas exchange.
It serves as a route for incoming and outgoing air and filtering debris and pathogens from the incoming air.
Blocking the structures of the conducting zone would prevent delivery of air to and from the lungs impairing gas exchange.
In order to compensate for the reduction in gas exchange in the respiratory system, ventilation will increase
