The descending aorta is considered the thoracic aorta from T__ to T__.
T5 - T12
The descending aorta is considered the abdominal aorta from T__ to L__.
T12 or the level of the diaphragm to L4
At L4 the abdominal aorta divides into what?

The aorta is divided into segments, each named according to two systems. What are these 2 systems?
System I is the path that the aorta follows as it courses through the body.
- Ascending aorta
- Arch of the aorta
- Descending aorta
System II is the path named according to location within the body cavities.
- Thoracic aorta
- abdominal aorta
