Answer to Question 1

ANS: A
The most common type of epithelia is the numerous pseudostratified, ciliated, columnar epithelia.

Answer to Question 2

ANS: A
Low-velocity gas movement at the level of the terminal bronchiole and beyond is physiologically important for two reasons. First, laminar flow develops, which minimizes resistance in the small airways and decreases the work associated with inspiration. Second, low gas velocity facilitates rapid mixing of gases.
