Lymphatics. 267 



020. The Lymphatics of the 

 Testis and Epididymis. 



The lymphatics of the lumbar region 

 and the viscera form the double lumbar 

 plexus and the single mesenteric 

 plexus; from these the two Trunci lym- 

 phatici lumbales and the single Truncus 

 hjmpliaticus intestinalis are formed. 



a) The lumbar plexuses lie 

 upon the muscles of the lumbar region 

 and the lumbar portion of the spinal 

 column and form 20 30 lumbar 

 glands, partly superior and partly 

 inferior. Besides these plexuses the 

 glands 'receive the following lymphatics : 



The lymphatics of the testicle 

 from the testis and its coverings, in the 

 female from the ovary; in the latter, the 

 lymphatics of the fundus of the uterus 

 and the Fallopian tubes also open ; 



The lymphatics of the kid- 

 ney and suprarenal capsule; 



The lumbar lymphatics from 

 the lateral abdominal wall; 



The lymphatics of the s i g- 

 m o i d flexure and rectum on the 

 left side. 



b) The mesenteric or coeliac plexus is single, surrounds 

 the aorta and its upper branches, also the portal vein and forms 

 16 20 coeliac glands.
