AB The  aorta  is  the  largest  artery  in  the  body  and  connects  the  heart  to  the  systemic  vascular  bed.  It  consists  of  both  a  thoracic  and  an  abdominal  portion,  which  are  delineated  by  the  ligamentum  arteriosum.  The  thoracic  aorta  begins  at  the  aortic  valve  and  has  four  segments:  the  aortic  root,  ascending  aorta,  aortic  arch,  and  descending  aorta.  These  segments  originate  connections  with  several  critical  vessels  including  the  coronary,  innominate,  subclavian,  and  carotid  arteries.  Similarly,  the  abdominal  aorta,  which  begins  as  the  vessel  travels  through  the  diaphragm,  gives  rise  to  the  celiac,  superior  mesenteric,  inferior  mesenteric,  and  renal  arteries  and  ultimately  bifurcates  into  the  common  iliac  arteries.
