MAJOR VESSELS OF THE THORAX, ABDOMEN, AND PELVIS
The descending thoracic aorta is the continuation of the aorta beyond the aortic arch. Branches of the descending aorta include the bronchial, esophageal, phrenic, intercostal, and subcostal arteries. The ab- dominal aorta begins at the level of the 12th thoracic
vertebra as it passes through the aortic hiatus of the diaphragm (Fig. 1-15). There are three major branches of the anterior aspect of the abdominal aorta. The first branch is the celiac artery. This is also known as the celiac trunk or celiac axis. It is a fairly short vessel, only 1–2 cm in length. It gives rise to the hepatic, splenic, and left gastric arter- ies (Fig. 1-16). The superior mesenteric artery is the
