<h3>
What is thoracic duct?</h3>
- The largest lymphatic channel in the body's lymphatic system is the thoracic duct, commonly known as van Hoorne's canal.
- Adults have an average length of 40 cm, and their abdominal origin is about 5 mm wide.
- 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.
- The primary lymphatic channel for the return of chyle/lymph to the systemic venous system is the thoracic duct.
- It drains lymph from the left side of the face and neck, left hemithorax, left upper limb, and both lower limbs.
