The thoracic duct carries chyle, a liquid containing both lymph and emulsified fats, rather than pure lymph. The thoracic duct ascends through the aortic hiatus of the diaphragm entering the posterior mediastinum, still to the right of the vertebral column. The termination may be at a different site –, Multiple nodes of entry at the above locations. Any of the small excretory ducts of the lacrimal glands. Return excess interstitial fluid (tissue fluid) to the bloodstream. The remaining 5% include termination in the external jugular vein, vertebral vein, brachiocephalic vein, suprascapular vein, and transverse cervical vein.
The right lymphatic duct receives lymph from only the upper right side of the body. Left lymphatic duct; Alimentary duct; Chyliferous duct; Van Hoorne’s canal.

It unites with the hepatic duct from the liver to form the common bile duct.
Returning lymph to the bloodstream helps to maintain normal blood volume and pressure. It eventually disappears, its point of origin being indicated as a pit, the foramen cecum. When embryologic lymphatic trunks converge above the T12 vertebral level, the cisterna chyli is generally absent, but there may be dilation of lower lumbar trunks. A tube through which various substances can pass. Anatomy, Thorax, Mediastinum Superior and Great Vessels.

The wall of the thoracic duct has three layers: the intima, the media, and the adventitia. Healthline Media does not provide medical advice, diagnosis, or treatment. The two lymphatic ducts of the body are the right lymphatic duct and the thoracic duct. At the junction of the lymphatic and venous system, a bicuspid valve prevents venous backflow into the lymphatic system 3). The vessel usually starts from the level of the twelfth thoracic vertebrae (T12) and extends to the root of the neck. A duct of the pancreas leading into the pancreatic duct or the duodenum near the mouth of the common bile duct. The thoracic duct is the largest lymphatic vessel within the human body, and plays a key role in the lymphatic system.
Much like other lymph nodes located throughout…, Lymph nodes are small, round organs of the lymphatic system that support proper functioning of the immune system. In about 20% of people, these ducts join to form a short right lymphatic duct.
Collecting ducts: Lymphatic vessels empty the lymph into the right lymphatic duct and left lymphatic duct (also called the thoracic duct). Synonym: A branch of a respiratory bronchiole that leads directly to the alveolar sacs of the lungs.
In human anatomy, the thoracic duct is the larger of the two lymph ducts of the lymphatic system. This is where lymph fluid reaches the end of its journey from the interstitial space of tissues back into blood circulation. It travels through the aortic aperture diaphragm and rises along the posterior mediastinum.
It sometimes persists as an anomaly.
When the duct ruptures, the resulting flood of liquid into the pleural cavity is known as chylothorax. Synonym: Any of a class of ducts within the lobules of glands, esp.
There are also two valves at the junction of the duct with the left subclavian vein, to prevent the flow of venous blood into the duct. See: In the embryo, a duct that connects the thyroid diverticulum with the tongue.
Front photo of the Ductus Thoracicus in the Human mediastinum with the heart and part of the pericard removed. The thoracic duct may lie on the left side of the aorta in its entire length to open in the left venous system in 4% of cases.
The thoracic duct carries chyle, a liquid containing both lymph and emulsified fats, rather than pure lymph. In the embryo, a tubular projection of the otocyst ending in a blind extremity, the endolymphatic sac. The other duct is the right lymphatic duct.
Lymphatic ducts empty lymph fluid into the venous system. anterior to right posterior intercostal arteries and termination of hemizygos and accessory hemiazygos vein.
When it is joined by the three trunks, the thoracic duct drains three-quarters of the body: the left side of the head, neck, and thorax; the left upper limb; and the body’s entire lower half (see Figure 2). Their coiled portions constitute the lobuli epididymidis. The main lymphatic duct, originating at the cisterna chyli. posterior to arch of aorta and left subclavian artery, double thoracic ducts (i.e. Lymphatic vessels merge to create the lymphatic ducts which drain into the venous system. The thoracic duct is the main lymphatic channel for the return of chyle to the venous system. In females it develops into the oviducts, uterus, and vagina; in males it degenerates to form the appendix testis. (Thoracic duct is thin vertical white line at center.). The overall drainage system of the body is asymmetrical (see Figure 3).
adj.. A tubular structure giving exit to the secretion of a gland or organ, capable of conducting fluid.
Lymph capillaries are tiny, thin-walled vessels, closed at one end and located in the spaces between cells throughout the body.
From it develop the ductus epididymis, ductus deferens, seminal vesicle, ejaculatory duct, ureter, and pelvis of the kidney. These disease states include congestive heart failure, cirrhosis or the liver, portal hypertension, and malignancy 4).
Front photo of the Ductus Thoracicus in the Human mediastinum with the heart and part of the pericard removed. In adults, the thoracic duct transports up to 4 L of lymph per day.[4].
When there is an obstruction of the thoracic duct, lymph collects in the pleural cavity.
The thoracic duct drains a much larger portion of the body than does the right lymphatic duct. They lie within the epididymis and connect the rete testis with the ductus epididymidis. 2016 Dec;38(10):1143-1151, Sarkaria IS, Finley DJ, Bains MS, Adusumilli PS, Rizk NP, Huang J, Downey RJ, Rusch VW, Jones DR.
