The first and often largest visceral branch of the abdominal aorta is the
celiac trunk
celiac trunk
The celiac trunk, also known as the celiac artery, is a short vessel that arises from the aorta and passes below the median arcuate ligament, just as the aorta enters the abdomen at the level of the T12 vertebra. The celiac trunk measures about 1.5cm to 2cm in length.
