Answer to Question 1

ANS: B
The adult trachea is approximately 12 cm long and has an inner diameter of about 2.0 cm.

Answer to Question 2

ANS: A
At the base of the trachea, the last cartilaginous ring that forms the bifurcation for the two bron-chi is called the carina. The carina is an important landmark that is used to identify the level at which the two main stem bronchi branch off from the trachea.
