- The thoracic duct runs from the root of the neck to the twelfth thoracic vertebra.
- The thoracic duct enters the posterior mediastinum, remaining to the right of the vertebral column, by ascending via the diaphragm's aortic hiatus.
- At the T7 vertebral level, it runs posterior to the esophagus before crossing over to the left side of the thorax at the T5 vertebral level.
