The alveolus is the site of gas exchange in the lungs where oxygen is exchanged for carbon dioxide.

Answer: B, G 
 The bronchiole and trachea are structures that are part of the respiratory system but are not directly involved in gas exchange. They serve to transport air into and out of the lungs.
