question 16
1 pts
anatomically, how does the right bronchus differ from the left bronchus, and what effect might this have on the aspiration of objects?
the right bronchus is the same size and shape as the left. therefore, aspiration of foreign objects can occur equally often in either bronchus.
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.

Explanation:

Question 15

The thoracic cavity is divided into the left pleural cavity, right pleural cavity, and the mediastinum. The respiratory cavity is not a division of the thoracic cavity.

Anatomically, the right bronchus is slightly larger and more vertical than the left. This anatomical feature makes it more likely for aspirated foreign objects to lodge in the right bronchus.

Answer:

respiratory cavity
