Drainage

The right duct drains lymph fluid from:
  • the upper right section of the trunk, (right thoracic cavity, via the right bronchomediastinal trunk),
  • the right arm (via the right subclavian trunk),
  • and right side of the head and neck (via the right jugular trunk),
  • also the lower lobe of the left lung.


All other sections of the human body are drained by the thoracic duct
Thoracic duct

In human anatomy, the thoracic duct is an important part of the lymphatic system—it is the largest lymphatic vessel in the body. It is also known under various other names including the alimentary duct, chyliferous duct, duct of Pecquet, the left lymphatic duct and Van Hoorne's canal....

History

The discovery of this structure has been credited to Niels Stensen.
