Circulatory Pathways Aorta: The largest artery in the body, the aorta arises from the left ventricle of the heart, goes up (ascends) a little ways, bends over (arches), then goes down (descends) through the chest and through the abdomen to where ends by dividing into two arteries called the common iliac arteries that go to the legs.natomically, the aorta is traditionally divided into the ascending aorta, the aortic arch, and the descending aorta. The descending aorta is, in turn, subdivided into the thoracic aorta (that descends within the chest) and the abdominal aorta (that descends within the belly).

Descending thoracic aorta The thoracic aorta is a part of the aorta located in the thorax. It is a continuation of the descending aorta and contained in the posterior mediastinal cavity.he thoracic aorta is a continuation of the descending aorta and becomes the abdominal aorta when it passes through the diaphragm. The initial part of the aorta, the ascending aorta, rises out of the left ventricle, from which it is separated by the aortic valve.

Aorta The aorta (/eɪˈɔrtə/) is the main 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). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.ne way of classifying a part of the aorta is by anatomical compartment, where the thoracic aorta (or thoracic portion of the aorta) runs from the heart to the diaphragm.

Picture of the Aorta The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle, the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve. Three leaflets on the aortic valve open and close with each heartbeat to allow one-way flow of blood. 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.

- Ascending aorta: The first section of the aorta, which starts from the left ventricle of the heart and extends to the aortic arch. The right and left coronary arteries that supply blood to the heart muscle arise from the ascending aorta.

Thoracic Aortic Disease Normal Aorta. An aneurysm is a swelling of the aorta, the main blood vessel of the body. The aorta begins just above the heart and rises straight up in the front of the chest (ascending aorta) toward the top of the body. At that level, it takes a turn, called the aortic arch, toward the back of the body.

Aortic arch The aortic arch, arch of the aorta or the transverse aortic arch is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea.

- Aortic Arch. As we continue to follow the aorta away from the heart, we see that it resembles an upside-down 'U.' This section is called the aortic arch, and it's the curved section of the aorta with branches that supply the brain, head, neck and arms.

Ascending aorta Components [edit]. The aortic root is the portion of the ascending aorta beginning at the aortic annulus and extending to the sinotubular junction. Between each commissure of the aortic valve and opposite the cusps of the aortic valve, three small dilatations called the aortic sinuses.The sinotubular junction is the point in the ascending aorta where the aortic sinuses end and the aorta becomes a tubular structure.etween each commissure of the aortic valve and opposite the cusps of the aortic valve, three small dilatations called the aortic sinuses.

Abdominal aorta The abdominal aorta is the largest artery in the abdominal cavity. As part of the aorta, it is a direct continuation of the descending aorta (of the thorax).tructure [edit]. The abdominal aorta begins at the level of the diaphragm, crossing it via the aortic hiatus, technically behind the diaphragm, at the vertebral level of T12. It travels down the posterior wall of the abdomen, anterior to the vertebral column.

Abdominal Aortic Aneurysm (AAA) What is an abdominal aortic aneurysm? The aorta, the largest artery in the body, is a blood vessel that carries oxygenated blood away from the heart. It originates just after the aortic valve connected to the left side of the heart and extends through the entire chest and abdomen.

Medical Definition of Descending aorta Like other sections of the aorta (the ascending aorta and aortic arch), the descending aorta is an arbitrary anatomic entity. The aorta is one continuous conduit that stems from the left ventricle of the heart to carry blood to most of the body.

Aortic arch For the embryological structure, see Aortic arches. The aortic arch, arch of the aorta or the transverse aortic arch (English pronunciation: /eɪˈɔrtɪk/) is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea.
