The thoracic duct ascends through the aortic hiatus of the diaphragm entering the posterior mediastinum, still to the right of the vertebral column. It courses posterior to the esophagus at the T7 level and crosses over the midline to the left side of the thorax around the T5 vertebral level.Jul 31, 2021
Where is the thoracic duct located?
The thoracic duct extends from the twelfth thoracic vertebra to the root of the neck. The thoracic duct is formed from the abdominal confluence of the left and right lumbar lymph trunks, as well as the left and right intestinal lymph trunks between T12 and L2.
Is the thoracic duct The left lymphatic duct?
In human anatomy, the thoracic duct is the larger of the two lymph ducts of the lymphatic system. It is also known as the left lymphatic duct, alimentary duct, chyliferous duct, and Van Hoorne's canal. The other duct is the right lymphatic duct.
What is the right thoracic duct?
The lymphatic vessels return the lymph to the venous system via two main channels: The right lymphatic duct drains the right thorax, upper limb, head and neck. The thoracic duct drains all lymph from the lower half of the body.
What happens when there is blockage in the main thoracic duct?
Obstruction of the thoracic duct(s) causes chronic upper extremity lymphedema. Lymphatics have bicuspid valves like the venous system. Metaplastic fibrosis resulting from obstruction of lymph drainage in the upper extremities impedes vertebral venous plexus / Batson's plexus circulation.
What does the left lymphatic duct drain?
The thoracic duct drains lymph into the circulatory system at the left brachiocephalic vein between the left subclavian and left internal jugular veins....Lymph ductSystemLymphatic systemDrains toSubclavian veinsIdentifiersLatinDuctus lymphaticus3 more rows
What would happen if the right lymphatic duct was blocked?
If the lymph vessels or nodes are blocked, removed or damaged, it can cause a build up of fluid. This can cause swelling, known as lymphoedema.
What does the thoracic duct do?
The thoracic duct is the main lymphatic vessel for the return of chyle/lymph to the systemic venous system. It drains lymph from both lower limbs, abdomen (except the convex area of the liver), left hemithorax, left upper limb and left side of face and neck.
What are the 2 main lymphatic ducts?
The two major lymphatics of the body include the right lymphatic duct and the thoracic duct. The right duct drains most of the right upper quadrant whereas the thoracic duct drains the lower body including the extremities and abdomen.
Where do the right and left lymphatic ducts drain?
The thoracic duct drains into to the left subclavian vein while the right duct drains into the right subclavian vein, both at the junction between the respective vein and the jugular vein.
Where do the thoracic and right lymphatic ducts deliver lymph?
The thoracic duct delivers lymph into junction between left subclavian and left internal jugular veins. Right lymphatic duct delivers lymph into junction between right subclavian and right internal jugular veins.
Where do the thoracic duct and right lymphatic duct drain into?
A one-way valve at this location prevents blood from entering the thoracic duct. The right lymphatic duct drains into the right subclavian vein.
