Question

Quizplus · Accepted Answer

Contraction of the diaphragm actually causes inhalation to occur, not exhalation. During inhalation, the diaphragm contracts and moves downward, creating a vacuum in the chest cavity and pulling air into the lungs. During exhalation, the diaphragm relaxes and moves upward, pushing air out of the lungs.
