The abdominal aorta enters the abdomen through the diaphragm at the level of the twelfth thoracic vertebre and continues to just below the umbilical area, where it splits into the right and left common iliac arteries. The aorta supplies oxygenated blood to most of the body.
The aorta can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta and the abdominal aorta. It terminates at the level of L4 by bifurcating into the left and right common iliac arteries.
The abdominal aorta enters the abdomen posterior to the median arcuate ligament and lies anterior and slightly to the left of the anterior aspect of the lumbar vertebrae, with the inferior vena cava lying to its right.
What is the anatomy of the aorta? The aorta has many sections, including the: Aortic root: Section that attaches to the heart. This is the widest part of the aorta. Aortic valve: Three flaps of tissue (leaflets) that snap open and shut to release oxygen-rich blood from the heart.
The abdominal aorta emerges from the aortic orifice of the diaphragm at the level of T12 vertebra. It begins its course anterior and to the left of the vertebral column and continues downwards for about 10 cm.
In human anatomy, 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). [1]

The abdominal aorta begins at T12 and ends at L4, where it divides into the right and left common iliac arteries. It enters the abdomen through the aortic opening of the diaphragm, which is located beneath the median arcuate ligament between the crura of the diaphragm at T12.
The thoracic aorta consists of the ascending aorta, aortic arch, and descending aorta. The descending thoracic aorta passes through the diaphragm’s aortic hiatus at the T12 vertebral level at which point it continues as the abdominal aorta.
