Question

Quizplus · Accepted Answer

As you ascend to higher altitudes, the atmospheric pressure decreases. This makes it harder for air to enter your lungs during inhalation because there is less pressure pushing the air in. Therefore, you would need to work harder to expand your thoracic size beyond what is normal to inhale the same amount of air. Exhalation, on the other hand, should not be affected as much as inhalation.
