Question

multiple choice question
the ____ aorta arises from the left ventricle while the ____ aorta passes through the thoracic and abdominal cavities.

ascending, descending
descending, ascending

Explanation:

To solve this, we recall the anatomy of the aorta. The ascending aorta starts from the left ventricle. The descending aorta runs through the thoracic (thoracic part of descending aorta) and then abdominal (abdominal part of descending aorta) cavities. So the correct pair is ascending (first blank) and descending (second blank).

Answer:

A. ascending, descending
