Question 1

What is the progression of the aorta?

Answer 1

It begins distal to the left ventricle and aortic valve, travels superiorly as the very short ascending aorta, turns left as the aortic arch, then travels inferiorly as the descending aorta through the thorax (thoracic aorta), through the aortic hiatus on the thoracic diaphragm, and into the abdomen as the abdominal aorta.
