Thoracic duct Quick Reference: The large lymph vessel that begins at the cisterna chyli which is a sac lying adjacent to the aorta in the aortic opening of the diaphragm. Into this drains the right and left lumbar lymph trunks draining the lower limbs and intestinal trunk. From here the thoracic duct runs up through the thorax to the neck and comes to lie on the right side of the oesophagus. The lymph carried by the thoracic duct runs into the subclavian vein.
