298 THE VASCULAR SYSTEMS 



The lymphatics of the lower limb are arranged in a super- 

 ficial and a deep set. The former open, in general, into the 

 superficial inguinal nodes; the latter into the deep inguinal 

 nodes. The superficial follow, in a general way, the course 

 of the long saphenous vein; the deep accompany the deep 

 bloodvessels, and in the leg enter the popliteal nodes; in the 

 gluteal and adductor region some enter the internal iliac nodes. 



The superficial lymphatics of the lower part of the trunk 

 also join the superficial inguinal nodes. The superficial lymph- 

 atics of the penis enter the superior set of superficial inguinal 

 nodes; the deep run under the pubic arch to join the internal 

 iliac nodes. The superficial lymphatics of the scrotum join 

 the superficial inguinal nodes. In the female external genitalia 

 a similar disposition obtains. 



The superficial inguinal nodes, eight or ten, consist of a 

 superior or oblique set in the line of Poupart's ligament, and 

 an inferior or vertical set lying around the upper part of the 

 saphenous vein. Efferent vessels join the deep inguinal and 

 external iliac nodes. 



The four or five popliteal nodes surround the vessels, and 

 receive the deep and some superficial absorbents of the leg. 



The deep inguinal gland* lie around the femoral vessels; 

 one at the crural ring is constant. 



THE LYMPHATIC VESSELS AND NODES OF THE PELVIS 



AND ABDOMEN 



These include the following: 



Six or more external iliac nodes surround these vessels. 



Numerous internal iliac nodes, and sacral glands on the 

 face of the sacrum. 



The lymphatics of the bladder enter the internal iliac nodes 

 with the pr astatic branches. 



The lymphatics of the uterus, with those of the vagina, to 

 the internal iliac nodes. 



The lymphatics of the rectum enter the sacral node.
