n this study, aimed to determine large Iymphatic ducts in the New Zealand rabbit, a tota'l of iO adult rabbi ts were used. Pattern of the lymphatic ducts was observed by injecting patent blue into the capsula of known lymph nodes. Tracheal tnınk, the largest lymphatic vessel of neck region, is formed by the efferent vessel of retrophaıY~lgeal lymph node. This lymph vessel is directed towards the efferent vessel of retropharyngeal lymph node. it courses towards cran:ial thoracic aperture in paraııel to common carotid artery, vagus nerve, and internal thoracie vein. It has been determined that tracheal tnınk and effereııt lymphatic vessel of the superficial cervical lymph nodes united on the right side, then it is called right lymphatic ducr and met the lymphatic vessel coming from the thoracic limb, arrived i em forward and finally joined to right cranial vena cava. As far the left side, traeheal tnınk and efferent lymphatic vessel of the superficial cervical Iymph nodes united and then together with the Iymphatic vessel from the thoracic limb it joined to thoracic duct. The vessel met ductus thoracieus at the eaudal to the first costa and joined to left cranial vena cava approximately 50 mm later. The thoraeic duct, beginning in the cisterna chyli, lies ventral to the verteb.ral column and enters to the thoracic cavity via the aortic hiatus. The thoracic duct was determined advancing cranially between the vertebral column and thoracic aorta. thus ending in the left cranial ve na cava
