Where is ductus Thoracicus 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.

Where does ductus Thoracicus drain?

The thoracic duct usually starts from the level of the twelfth thoracic vertebrae (T12) and extends to the root of the neck. It drains into the systemic (blood) circulation at the junction of the left subclavian and internal jugular veins, at the commencement of the brachiocephalic vein.

Which collecting duct is associated with the cisterna chyli?

The cisterna chyli is the abdominal origin of the thoracic duct, and it receives the bilateral lumbar lymphatic trunks.

What is the function of the cisterna chyli?

It receives fatty chyle from the intestines and thus acts as a conduit for the lipid products of digestion. It is the most common drainage trunk of most of the body’s lymphatics. The cisterna chyli is a retro-peritoneal structure.

Why is the lymph in the cisterna chyli white in color?

The intestinal trunk also transports fluid to the cisterna chyli from the small intestines. After a meal, due to the absorption of fat into the intestinal trunk, the contents of the intestinal lymph vessels appear cloudy (milky white) in color.

Where is the cisterna chyli and what is its significance in the lymph system?

The cisterna chyli is a large midline lymphatic collecting structure located just inferior to the aortic hiatus of the diaphragm. It collects lymphatics from the lower extremities via left and right lateral branches and from the intestinal tract via an intestinal branch.

What parts of the body are drained by the thoracic duct?

The thoracic duct drains the lower extremities, pelvis, abdomen, left side of the thorax, left upper extremity, and left side of the head and neck. It originates at the cisterna chyli (when present) and terminates at the junction of the left subclavian and left internal jugular veins.

Does cisterna chyli pass through the diaphragm?

The cisterna chyli receives the lymphatic drainage in the abdomen, just posterior to the aorta. It passes through the aortic hiatus of the diaphragm, where it continues as the thoracic duct.

Where is your cisterna chyli?

thoracic duct
The cisterna chyli is a dilated lymphatic sac in the retrocrural space. It is located at the origin of the thoracic duct and is seen in approximately 50% of lymphangiographic studies (,1) and 20% of autopsies (,2).

Is cisterna chyli second heart?

cisterna chyli is supposed to be the second heart of humans… In the abdomen, cleansed lymph from the intestines is collected in the cysterna chyli, and, except for the upper R quadrant of the body, is collected into the thoracic duct which empties into the circulatory system through the L subclavian vein .
