celiac (lymphatic) plexus

ce·li·ac (lym·phat·ic) plex·us

a network formed of the efferent and afferent lymphatic vessels of the celiac lymph nodes and related to the celiac trunk; the afferent lymphatic vessels bring lymph primarily from structures served by the celiac artery (stomach, duodenum, pancreas, and visceral aspect of the liver); the efferent vessels drain into the cisterna chyli/thoracic duct via the intestinal lymph trunks.
