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]

2025年2月4日 · The abdominal aorta is a continuation of the thoracic aorta beginning at the level of the T12 vertebrae. It is approximately 13cm long and ends at the level of the L4 vertebra. At this level, the aorta terminates by bifurcating into the right and left common iliac arteries that supply the lower body.

The abdominal aorta (Latin: aorta abdominalis) is the abdominal part of the descending aorta and the largest artery in the abdomen. It is the continuation of the thoracic aorta (thoracic part of the descending aorta) after it enters the abdomen via the aortic hiatus of the diaphragm.

2023年7月25日 · The abdominal aorta terminates as it bifurcates into common iliac arteries, which subsequently provide arterial supply to the pelvis and lower limbs. [1] [2] The aorta receives nutrient-rich blood from the left ventricle after blood is ejected through the aortic valve.
