Answer to Question 1

ANS: B
The increase in airway diameter with increasing lung volume decreases airway resistance.

Answer to Question 2

ANS: A
Laminar flow is affected by gas flow, viscosity of the gas, tube radius, and length. Turbulent flow is most affected by gas density and viscosity, linear velocity, and tube radius.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
