HUMAN ANATOMY. 



the left testis pass lie immediately beneath the level of the renal veins, while those 

 in which the stems from the right testis terminate are lower, being situated about 

 midway between the level of the renal vein and the junction of the common iliac \eins. 



The lymphatics of the vas deferens are probably arranged in two net-works, 

 one belonging to the mucosa and the other to the muscular coat, although so far only 

 the latter net-work has been demonstrated. At the testicular end of the duct the 

 net-work communicates with that of the epididymis, and the stems which arise from 

 it accompany those of the testis to the lateral lumbar nodes. At the vesical end 

 the net-work communicates with that of the seminal vesicles and its efferents pass 

 to one of the hypogastric nodes. 



The lymphatics of the seminal vesicles are much more readily demonstrable 

 than those of the vasa deferentia. They arise from two net-works, one of which is 

 situated in the mucosa and the other in the muscularis. Stems from the latter form 

 a third net-work over the surfaces of the vesicles and from this ef?erents, two or three 

 in number, pass to some of the hypogastric nodes.

surrounding each of the Graafian follicles. The stems which arise from these net- 

 works converge toward the hilus, where they form a rich plexus and from this from 

 six to eight efferents arise and follow the ovarian blood-vessels to terminate in the 

 lateral lumbar nodes (Fig. 828). 



Owing to thinness of the walls it is difficult to distinguish a definitely layered 

 arrangement of the lymphatic net-work of the Fallopian tubes. It is, however, 

 rich, and communicates with that of the fundus of the uterus. It gives rise to two or 

 three efferents which accompany the ovarian ef?erents to the lateral lumbar nodes.
