Which structure lies immediately anterior to the retrosternal clear space?

Open full view ↗
Retrosternal aerated lung lies behind the sternum. The lateral projection separates anterior and posterior chest structures.
Take this to your next question: the retrosternal space is behind the sternum. Connect that relationship to the image, then compare the alternatives.
Why the other answers don’t fit
- Thoracic vertebral bodies
The spine is posterior. - Esophagus
The esophagus does not form this anterior boundary. - Descending thoracic aorta
The descending aorta is posteriorly situated. - Sternum
The retrosternal space is behind the sternum.
