ductus arteriosum
Ascending aorta, arch of aorta and the descending aorta are located in your thoracic cavity.
The descending aorta.The aorta is divided in ascending, aortic arch, descending, thoracic, and abdominal.
Ascending, arch, descending thoracic and abdominal
The diaphragm divides the thoracic and abdominal aorta. These are both parts of the descending aorta, extending from the aortic arch.
The ductus arteriousus connects the pulmonary artery with the descending thoracic aorta, allowing the blood to enter into the fetal circulation without going through the lungs. This structure closes at birth and becomes the "ligamentum arteriosus."
