Question

Quizplus · Accepted Answer

Yawning is a non-respiratory air movement that is intended to ventilate all alveoli. It involves taking in a deep breath, which then causes a rapid and forceful exhalation of air, thereby increasing the amount of air exchanged in the lungs. Coughing, hiccupping, and sneezing are all respiratory air movements that involve expelling air from the lungs through the airways.
