Which more commonly traps a foreign object that has entered the respiratory passageways? A. Left primary bronchus because it is longer.. B. Right primary bronchus because it has a larger diameter. C. Left primary bronchus because it is more horizontal. D. Right primary bronchus because it is more horizontal. E. Left primary bronchus because it is shorter.

B. Right primary bronchus because it has a larger diameter.

Explanation:

Based on the answers listed it can be said that the one that more commonly traps a foreign object would be the Right Primary Bronchus. This bronchus is far wider, shorter and placed at a more vertical direction than that of the left brochus, this positioning allows it to trap any and most foreign objects as soon as they enter the passageways, way before the left bronchus.
