Answer to Question 1

ANS: D
Whether aerosol particles that are inhaled into the lung are deposited in the respiratory tract de-pends on the size, shape, and motion of the particles and on the physical characteristics of the airways and breathing pattern.

Answer to Question 2

ANS: A
Inertial impaction occurs when suspended particles in motion collide with and are deposited on a surface. This is the primary deposition mechanism for particles larger than 5 m.
