Answer 1

Answer:

d) When the diaphragm pushes upward, it decreases the volume of the lungs, pushing air out.

Explanation:

the relaxed diaphragm muscle is dome-shaped, the contracted muscle is horizontal.

Answer 2
D: When the diaphragm pushes upward, it decreases the volume of the lungs, pushing air out.

This is because the relaxed diaphragm is an upwards dome shape, upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm once again relaxes and returns to its original domelike shape, and air is forced out of the lungs.
