Main Model


Ascending aorta

The ascending aorta, approximately 2.5 cm in diameter, begins at the aortic orifice. Its only branches are the coronary arteries, arising from the aortic sinuses. The ascending aorta is intrapericardial; for this reason, and because it lies inferior to the transverse thoracic plane, it is considered a content of the middle mediastinum (part of inferior mediastinum).
