THE VASCULAR SYSTEMS 



prostatic portions, and those of the whole urethra in the female, pass to the internal 

 iliac nodes. 



4. The lymphatic vessels of the reproductive organs. 



The lymphatic vessels of the testes consist of two sets, superficial and deep, 

 the former commencing on the surface of the tunica vaginalis, the latter in the 

 epididymis and body of the testis. They form several large trunks which ascend 

 with the spermatic cord, and, accompanying the spermatic vessels into the abdo- 

 men, terminate in the lateral aortic nodes. 



The lymphatic vessels of the vas deferens pass to the external iliac nodes; 

 those of the vesiculae seminales partly to the internal and partly to the external 

 iliac nodes.

The lymphatic vessels of the ovary are similar to those of the testicle, and ascend 

 with the ovarian artery to the lateral aortic nodes. 



The lymphatic vessels of the Fallopian tube pass partly with those of the ovary 

 and partly with those of the uterus. 



The lymphatic vessels of the uterus (Fig. 1149) consist of two sets, superficial 

 and deep, the former being placed beneath the peritoneum, the latter in the sub- 

 stance of the organ. The lymphatics of the cervix uteri run in three directions 

 transversely to the external iliac nodes, postero-laterally to the internal iliac nodes, 

 and posteriorly to the common iliac nodes. The majority of the vessels of the 

 body and fundus of the uterus pass outward in the broad ligaments, and are con- 

 tinued up with the ovarian vessels to the lateral aortic nodes; a few, however, 

 run to the external iliac nodes, and one or two to the superficial inguinal nodes. 

 In the unimpregnated uterus the lymphatic vessels are very small, but during 

 gestation are greatly enlarged.
