Select one:

a. movement of hot air is increased due to the increased kinetic energy of the molecules

b. surface area of the turbinates allows for the transfer of moisture

c. large surface area of the turbinates allows for the transfer of heat away from the hot air molecules

d. rate of gas exchange is decreased due to the large number of blood vessels in the nose

2) Bronchoscopy is a surgical technique for viewing the interior of the airways, using sophisticated flexible fibre optic instruments. The procedure involves inserting a tube with a tiny camera on the end through the nose or mouth into the respiratory tract. 

  • a) if the flexible fibre optic instrument was inserted through the NOSE, list, in order, the parts of the respiratory system the camera would pass moving down to the lungs.
  • b) a doctor suspects her patient may have lung cancer. What is lung cancer and what would be one reason why a doctor would order this bronchoscopy for this patient?
