What is the abdominal aorta?

Aorta is the largest artery in the body. It is associated with the left ventricle of the heart and has the work to transmit oxygenated blood from the heart to other parts of the body. Aorta of the abdomen is the last part of the aorta and is located in the abdominal cavity. He takes blood from the aorta, through the suitcase and the abdominal organs and legs.

The left chamber and the thoracic aorta heart lead to the abdominal aorta that begins at the membrane. This artery then intersects the membrane at the T12 vertebral level. From there it descends along the rear wall of the abdomen in front of a column of vertebrates, after natural curvature of lumbar turnover and slightly placed left of the middle line of the body. It also lies parallel to Dolní Vena Cava, which is located on its right side.

abdominal branches aorta into three sets of smaller arteries that became narrower when they descend through the abdominal cavity. These three sets are known as visceral, parietal and terminal arteries. These branches of the abdominal aorta and their related vertebral levels are definitionthe woven as follows. From the vertebral level of T12, The Abdominal Aorta First Branches into the inferior phrenic and celiac arteries (T12), superior mesenteric and middle Suparenal arteries (L1), Renal and Gonadal Arteries (L2), Lumbar Artery (L1-L4) (L3), and the Median Sacral and Common Iliac Arteries (L4). At the L5 level, the artery is then divided to form two common iliac arteries that carry blood on the feet.

The most common disease involving abdominal aorta is the abdominal aortic aneurysm (AAA). Aneurysm is an extension (also known as dilatation) of blood vessels due to the weakness in the blood vessel. In the weak part of the aneurysm bulges and poses a serious risk of rupture. AAA is multi -rest in men, especially those age 60 and older. Approximately 5% of men over 60 years of age suffer from abdominal aortic aneurysms. Risk factors for AAA development include smoking cigarettes, hypertension, high cholesterol (hypercholesterolemia) and diabetes mellitus. Although there are several possible causes of AAA, the timeThe cause remains arteriosclerosis or hardening of arteries.
