The aorta is primarily located in the posterior mediastinum. The mediastinum is divided into three main compartments: the anterior, middle, and posterior mediastinum. The posterior mediastinum is where the thoracic aorta travels, running along the vertebral column and providing branches to the chest wall and organs as it descends. These anatomical features also include surrounding structures such as the esophagus and thoracic duct, which further define this area.

In contrast, the anterior mediastinum is located more anteriorly and contains structures such as the thymus gland and lymph nodes, while the middle mediastinum houses the heart and pericardium, along with the major vessels emerging from the heart, like the ascending aorta and pulmonary arteries. Focusing on the anatomy reveals how the aorta's position aligns specifically with the posterior mediastinal space.
