Answer to Question 1

ANS: D
The respiratory center in the brainstem controls respiration by transmitting impulses to the respir-atory muscles, causing them to contract and relax. Respirations are not controlled by the cerebral cortex, the thalamus, or the basal ganglia.

Answer to Question 2

ANS: B
Surfactant is produced by the type II alveolar cells. Surfactant is not produced by mu-cus-producing cells, alveolar macrophages, or goblet cells.
