Correct Answer is D
Explanation
A. is responsible for the pumping of O2 from the alveoli into the pulmonary capillaries: gas exchange occurs by diffusion, not nerve stimulation.
B. Is responsible for exhalation: exhalation is a passive process; phrenic nerve controls diaphragm contraction for inhalation.
C. Decreases thoracic volume: diaphragm contraction increases thoracic volume.
D. Causes the diaphragm to contract: the phrenic nerve innervates the diaphragm and stimulates its contraction for inhalation.
Correct Answer is A
Explanation
A. Superior/upper right lobe: Label #1 is at the top part of the right lung.

C. Superior/upper left lobe: The left lung has only two lobes: superior and inferior. The superior lobe of the left lung would be in the corresponding location to label #6.
