What is the unfolding of the aorta?
The term unfolded aorta refers to the widened and decreased curvature of the aortic arch on a frontal chest radiograph giving an ‘opened up’ appearance. It is one of the more common causes for apparent mediastinal widening and is seen with increasing age, usually associated with aortic calcification.
What is the transverse aorta?
The transverse aorta is defined as that portion of thoracic aorta extending from an imaginary line corresponding to the beginning of the origin of the innominate artery to an imaginary line corresponding to the end of the origin of the left subclavian artery.
What is the visceral aorta?
The abdominal aorta supplies visceral and parietal arteries that arise in three vascular planes before it bifurcates to form the common iliac arteries at the L4. The unpaired visceral arteries to the gastrointestinal tract include the celiac, superior mesenteric and inferior mesenteric arteries.
What are the divisions of the aorta?
The aorta can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta and the abdominal aorta. It terminates at the level of L4 by bifurcating into the left and right common iliac arteries.
What causes an aorta to enlarge?
When the aorta is weak, blood pushing against the vessel wall can cause it to bulge like a balloon (aneurysm). A thoracic aortic aneurysm is also called a thoracic aneurysm, and aortic dissection can occur because of an aneurysm.
What are the 3 branches of aorta?
The arch of the aorta has three branches: the brachiocephalic artery (which divides into right common carotid artery and the right subclavian artery), the left common carotid artery, and the left subclavian artery. These arteries provide blood to both arms and the head.
What are the three trunks of the aorta?
The aortic arch has three branches, the brachiocephalic trunk, left common carotid artery, and left subclavian artery.

Is aorta a vein?
The aorta (/eɪˈɔːrtə/ ay-OR-tə) is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries)….
