TRUE Concerning airflow in the lung is:
During scuba diving, the density of the air is increased because of the raised pressure, and therefore, airway resistance rises. The other choices are incorrect: Flow is most likely to be turbulent in large airways; The higher the viscosity, the less likely is turbulence to occur; Halving the radius of the airway increases its resistance 16-fold;
Flow is more likely to be turbulent in small airways than in the trachea
The lower the viscosity, the less likely is turbulence to occur
In pure laminar flow, halving the radius of the airway increases its resistance eight fold
Airway resistance increases during scuba diving
