Medical Definition of Abdominal aorta Abdominal aorta: The abdominal aorta is the final section of the aorta, the largest artery in the body. It is a continuation of the thoracic aorta. It begins at the diaphragm, and runs down to the point where it ends (by splitting in two to form the common iliac arteries).

Congenital Heart Defects Most aneurysms occur in the aorta, the main artery that carries oxygen-rich blood from the heart to the body. The aorta goes through the chest and abdomen. An aneurysm that occurs in the chest portion of the aorta is called a thoracic (tho-RAS-ik) aortic aneurysm.An aneurysm that occurs in the abdominal portion of the aorta is called an abdominal aortic aneurysm. Aneurysms also can occur in other arteries, but these types of aneurysm are less common.This article focuses on aortic aneurysms.ost aneurysms occur in the aorta, the main artery that carries oxygen-rich blood from the heart to the body.

Overview The aorta is the body's major blood vessel. It runs from your heart, through your chest, and to your abdomen where it divides to supply blood to your legs. An abdominal aortic aneurysm (AAA) is a blood-filled bulge or ballooning in a part of your aorta that runs through your abdomen.Over time, this bulge in your aorta can become weak, and the force of normal blood pressure can cause it to rupture.n abdominal aortic aneurysm (AAA) is a blood-filled bulge or ballooning in a part of your aorta that runs through your abdomen.

- ABDOMINAL AORTIC ANEURYSM OVERVIEW. An aortic aneurysm occurs when the walls of the main blood vessel that carries blood away from the heart (the aorta) bulge or dilate. An abdominal aortic aneurysm (AAA) is located in the abdominal area, near the navel (figure 1).Aneurysms can also occur in other areas of the aorta, but the abdomen is the most common site. Abdominal aortic aneurysms are not related to aneurysms of the blood vessels in the brain.BDOMINAL AORTIC ANEURYSM OVERVIEW.

What is an abdominal aortic aneurysm? The aorta extends upward from the top of the left ventricle of the heart in the chest area (ascending thoracic aorta), then curves like a candy cane (aortic arch) downward through the chest area (descending thoracic aorta) into the abdomen (abdominal aorta).ain is the most common symptom of an abdominal aortic aneurysm. The pain associated with an abdominal aortic aneurysm may be located in the abdomen, chest, lower back, or groin area. The pain may be severe or dull. The occurrence of pain is often associated with the imminent (about to happen) rupture of the aneurysm.

What is the function of the aorta? • 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. Like all arteries, the aorta's wall has several layers: • The intima, the innermost layer, provides a smooth surface for blood to flow across.

- The aorta is the largest artery in the body. It rises from the heart's left ventricle (the major chamber that pumps blood out of the heart) filled with oxygen-rich blood that travels throughout the body. The aorta itself goes from the heart through the diaphragm into the abdomen. Many smaller vessels branch off from it.

What is an abdominal aortic aneurysm? The aorta delivers oxygenated blood pumped from the heart to the rest of the body. The most common location of arterial aneurysm formation is the abdominal aorta, specifically, the segment of the abdominal aorta below the kidneys. An abdominal aneurysm located below the kidneys is called an infrarenal aneurysm.An aneurysm can be characterized by its location, shape, and cause.ain is the most common symptom of an abdominal aortic aneurysm. The pain associated with an abdominal aortic aneurysm may be located in the abdomen, chest, lower back, or groin area. The pain may be severe or dull.

Abdominal Aortic Aneurysm (Screening/Follow-up) Abdominal aortic aneurysm. An abdominal aortic aneurysm occurs when a lower portion of your body's main artery (aorta) becomes weakened and bulges. An abdominal aortic aneurysm is an enlarged area in the lower part of the aorta, the major blood vessel that supplies blood to the body. The aorta, about the thickness of a garden hose, runs from your heart through the center of your chest and abdomen. Because the aorta is the body's main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding.

Atherosclerosis in abdominal aorta may signal future heart attack, stroke OAK BROOK, Ill. - In a study of more than 2,000 adults, researchers found that two MRI measurements of the abdominal aorta -- the amount of plaque in the vessel and the thickness of its wall -- are associated with future cardiovascular events, such as a heart attack or stroke. Results of the study are published online in the journal Radiology.

Abdominal Aortic Aneurysm An abdominal aortic aneurysm (AAA) is a ballooning of part of the aorta that is within the tummy (abdomen). An AAA usually causes no symptoms unless it bursts (ruptures). A ruptured AAA is often fatal. An AAA less than 5.5 cm wide has a low chance of rupture.

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.

- The abdominal aorta is the portion that is located in the abdominal area between the renal arteries and the iliac bifurcation (split) and it travels down the frontal surface of the vertebral column (spine).he aorta is the main trunk of the arterial system that carries oxygenated blood from the heart to all points in the body. The aorta arises from the left ventricle of the heart and ends at the lumbar area where it divides to form the right and left common iliac arteries that run down each leg.

Anatomy Abdominal Aorta. The abdominal aorta is the largest artery in the abdomen that provides blood to the organs and tissues of the abdomen, pelvis, and legs. It descends from the thorax as a continuation of the thoracic aorta and branches several times to form the major arteries of the abdomen. The lumbar artery is a parietal artery that splits from the abdominal aorta inferior to the gonadal artery. 2  It provides blood to the tissues and muscles of the abdominal wall. 3  The inferior mesenteric artery is a visceral artery that arises inferior to the lumbar artery.

Medical Definition of Descending aorta Definition of Thoracic aorta. Thoracic aorta: The thoracic aorta is a section of the aorta, the largest artery in the body, within the chest. Specifically, the thoracic aorta is that part of the aorta that starts after the arch of the aorta and runs down to the diaphragm, the great muscle that separates the chest from the abdomen. The thoracic aorta gives off numerous branches that supply oxygenated blood to the chest cage and the organs within the chest.
