What is the main role of aorta

1.	What is the main role of aorta
Answer» The main role of aorta is to pump oxygenated blood from heart to all parts of body The aorta is the largest artery in the body. The aorta is a tube about a foot long and just over an inch in diameter. The aorta is divided into four sections:• The ascending aorta rises up from the heart and is about 2 inches long. The coronary arteries branch off the ascending aorta to supply the heart with blood.• The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms.• The descending thoracic aorta travels down through the chest. Its small branches supply blood to the ribs and some chest structures.• The abdominal aorta begins at the diaphragm, splitting to become the paired iliac arteries in the lower abdomen. Most of the major organs receive blood from branches of the abdominal aorta.
