Question 1

Anatomically, how does the right bronchus differ from the left bronchus, and what effect might this have on the aspiration of objects?

Accepted Answer

A)  The right bronchus is the same size and shape as the left. Therefore, aspiration of foreign objects can occur equally often in either bronchus. 
B)  The left bronchus is slightly larger and more vertical than the right. This anatomical fact helps explain why aspirated foreign objects frequently lodge in the left bronchus.
