lymphatics draining the lateral abdominal muscles and accompanying the lumbar 

 veins. Most of the efferent vessels of the lateral aortic nodes converge to form 

 the right and left lumbar trunks (trunci lumbales) which join the receptaculum 

 chyli, but some enter the preaortic and retroaortic nodes, and others pierce the 

 crura of the Diaphragm to join the lower end of the thoracic duct. The preaortic 

 nodes lie in front of the aorta, and may be divided into cceliac, superior mesenterie, 

 and inferior mesenteric groups, arranged around the origins of the corresponding

arteries. They receive a few vessels from the lateral aortic nodes, but their 

 principal afferents are derived from the viscera supplied by the three arteries 

 with which they are associated. Some of their efferents pass to the retroaortic 

 nodes, but the majority unite to form a common trunk, the truncux infcxtiiial/*, 

 which enters the receptaculum chyli. The retroaortic nodes are placed below 

 the receptaculum chyli, on the bodies of the third and fourth lumbar vetebnr. 

 They receive lymphatic trunks from the lateral and preaortic nodes, while their 

 efferents terminate in the receptaculum chyli. 



The Lymphatic Vessels of the Abdomen and Pelvis. 



The lymphatic vessels of the walls of the abdomen and pelvis may be divided 

 into two sets, superficial and deep. 



The superficial vessels follow the course of the superficial bloodvessels and 

 converge to the upper group of the superficial inguinal nodes. Those derived 

 from the integument of the front of the abdomen below the umbilicus follow
