What is cisterna chyli?

Hint:Cisterna chyli is a dilated lymph channel that is generally located opposite the first and second lumbar vertebrae. It marks the starting point of the thoracic duct. It is also known as “Receptaculum Chyli”.

Complete answer:
>Cisterna duct is located in the lumbar region of the abdominal cavity. It is a common drainage trunk for the body’s lymphatic system. It transverse the lower body from the upper body, situated to the right of the abdominal aorta at the back wall of the abdominal cavity, it is a large vessel. Its length is about. It forms a thoracic duct which transports lymph and chyle from abdomen to the junction of left subclavian vein and internal jugular veins through aortic opening of the Diaphragm.
>Cisterna chyli is a sac- like elongated structure at the junction of liver, lumbar, intestinal and descending intercostal lymphatic trunks.
>It receives lymph from the abdominal viscera as well as the abdominal wall. Cisterna chyli contains lymph as well as other body fluid found in the lymphatic system (i.e. lymph fluids).
>If cisterna chyli is accidentally ruptured it causes blood clotting, intestinal problems and dilated veins in legs and abdomen, possibly in the whole trunk.
>The main function of this ductal structure is the transport of ingested fat, approximately lymph per is transported through this channel.

Note: Cisterna chyli which is a saccular dilation of the main lymphatic trunk, is commonly situated behind the left crus of the diaphragm. It receives fatty chyle from the intestine and thus acts as a conduit for lipid products of digestion.
