What nonrespiratory air movement helps to clear the upper respiratory passageways?Multiple ChoiceYawningLaughingCoughingSneezing

To determine which nonrespiratory air movement helps to clear the upper respiratory passageways, we can analyze each of the options:

1. Yawning: This is primarily a form of deep inhalation that increases oxygen intake. It does not serve to clear the upper respiratory tract.

2. Laughing: Though this involves air movement, it is more of an emotional response and does not primarily function to clear the respiratory passages.

3. Coughing: This is a reflex action that helps to clear materials from the air passages, including mucus, dust, and other irritants.

4. Sneezing: This is another reflex action that expels air forcefully from the lungs to clear the nasal passages of irritants.

Conclusion

Both coughing and sneezing serve to clear the respiratory passages, but coughing specifically targets the clearance of the upper respiratory tract. Therefore, the most appropriate answer to the question is Coughing.
