Question

Air pressure is highest in the lungs during which of the following points?

Select one:
a. Beginning of inspiration, when lung volume is lowest
b. Beginning of expiration, when lung volume is lowest

Answer 1

I know the answer is not at the end of inspiration when lung volume is lowest so, it must be at the beginning of expiration, when lung volume is lowest. However, when I looked up expiration and inhaltion, it made it seem like inspiration was the answer...

Answer 2

Beginning of expiration, when lung volume is lowest
