(āôr`tə), primary artery of the circulatory systemcirculatory system,
group of organs that transport blood and the substances it carries to and from all parts of the body. The circulatory system can be considered as composed of two parts: the systemic circulation, which serves the body as a whole except for the lungs, and the

 in mammals, delivering oxygenated blood to all other arteries except those of the lungs. The human aorta, c.1 in. (2.54 cm) in diameter, originates at the left ventricle of the heartheart,
muscular organ that pumps blood to all parts of the body. The rhythmic beating of the heart is a ceaseless activity, lasting from before birth to the end of life. Anatomy and Function

The human heart is a pear-shaped structure about the size of a fist.

. After supplying the coronary arteries that nourish the heart itself, the aorta extends slightly toward the neck to feed branches serving the head and arms. It then arches down toward the waist, directing blood into the arterial system of the chest. Entering the abdomen through the aortic hiatus, an opening in the diaphragm, the aorta branches off to supply the stomach, kidneys, intestines, gonads, and other organs through extensive arterial networks. It finally divides into the two iliac arteries carrying blood to the legs. The elasticity of the aorta wall permits it to pulse in rhythm with the heartbeat, thus helping to propel blood through the body.



the main artery of the greater circulatory system, which supplies blood to all organs of the body.

The wall of the aorta consists of three membranes, that is, the interior (a layer of endothelial cells), intermediate (numerous rows of elastic fibers), and exterior (bundles of connective tissue fibers). Because of the elasticity of the aorta’s walls an uninterrupted flow of blood in the arteries is assured. In man, mammals, and birds, the aorta emerges from the left ventricle of the heart, forming an enlargement at its very beginning, called the aortic spindle, goes up (ascending aorta), turns back and to the left in man and mammals (arch of the aorta) and back and to the right in birds, and goes down (descending or dorsal aorta). In reptiles there are two aortic arches, that is, the right, or arterial, arch, emerging from the left ventricle of the heart; and the left, or venous, arch from the right ventricle. When they unite, they form a common aorta with mixed blood. In amphibians an arterial cone emerges from the only ventricle, and from it one pair (in ecaudates) or two pairs (in caudates) of aortic arches branch out, which form the dorsal aorta when they unite. In fishes and cyclostomes the ventricle passes into the abdominal aorta, which carries venous blood through the system of arterial arches into the gills (in fishes) and gill pouches (in cyclostomes). The blood which is oxygenated there is collected in the dorsal aorta. Of the invertebrates, mollusks and arthropods have aortas.

Furthermore, anatomical grouping of more levels was operated for compartmental comparison of the median of quantitative parameters, as follow: a) thoracic aorta, including from aortic valve to descending aorta (levels 1, 2, and 3 of quantitative analysis); b) abdominal aorta, including diaphragmatic aorta and aorta at the level of renal arteries origin (levels 4 and 5 of quantitative analysis).
In our study, we emphasize the observation of hyperdense adrenal glands and low-calibrated abdominal aorta signs in all patients whose imaging reveals CT hypoperfusion complex (sensitivity: 100%; specificity: 100%).
10 Contrarily, EVAR is performed under real-time monitoring to lead an appropriate covered stent into the abdominal aorta through the femoral artery, aiming to cover the proximal-and distal-end aneurysm necks.
In our patient, thrombosis was present in the abdominal aorta.
Abdominal aorta zones of injury were classified into three different zones according to surgical approaches: zone I (diaphragmatic hiatus to superior mesenteric artery (SMA)), zone II (includes SMA and renal arteries) and zone III (from the inferior aspect of the renal arteries to the aortic bifurcation).
According to coronary CT angiography result and clinical signs and symptoms we decided to examine the abdominal aorta and inferior limbs using CT angiography.
Finally, HLE was applied per gavage to rabbits and the influences on abdominal aorta and carotid artery, heart rate, blood pressure and blood glucose level were investigated.
For several years, surgeons have been using minimally invasive techniques to implant a stent graft--a fabric tube enmeshed in a metal framework--for repair of less complex aneurysms of the lower abdominal aorta or the descending thoracic aorta, two regions of the aorta without branch vessels that supply blood to critical abdominal organs.
The CTA incidentally depicts a common origin for the celiac axis and SMA from the abdominal aorta (celiacomesenteric trunk) (Figures 1, 2).
During the TTE examination the remaining portions of the aorta were also visualized: the aortic arch and thoracic aorta were of normal calibration, but the abdominal aorta was severely dilated and partially thrombosed (Video 2.
It was arising from the lateral aspect of abdominal aorta about 1.
