A.) healthy lungs B.) obstructive pulmonary disease C.) exposure to asbestos D.) restrictive disease D The functions of the nasal conchae are to enhance the air turbulence in the cavity and to increase the mucosal surface area exposed to air for greater efficiency.

A.) surface tension B.) air pressure C.) surfactant D.) friction D Which of the following is responsible for holding the lungs to the thorax wall?
