is the main artery
of the body which distributes blood, which is oxygenated in the lungs, to the different organs. People can be prone to calcification
of the aorta in the lining, but particularly in the aortic arch, the thoracic aorta, and the abdominal aorta. This aortic calcification is often discovered during a chest X-ray performed for other reasons because calcium is radiopaque (visible in X-rays). The consequences of aortic calcification may include a slowing of blood circulation, but are generally responsible for few clinical signs.
