Common iliac (see external iliac) : from base of sacrum to 

 terminate on 5th lumbar vertebra, a little to the right of the 

 middle line, where, with its fellow of opposite side, it forms 

 vena cava inferior. The right vein is the shorter, and nearly 

 vertical. Receives ilio-lumbar and sometimes lateral sacral 

 veins. Middle sacral empties into left common iliac. No 

 valves. 



Relations. Right vein passes behind, and then to right 

 side of artery. Left vein is placed on inner side of left artery, 

 and then passes behind right common iliac artery to join 

 right vein, crossing middle sacral artery. 



THE ABSORBENT SYSTEM.

 limbs, abdomen, except upper surface of liver, from left half 

 of thorax, left upper limb, and left side of head and neck. 



Length. 15 to 18 inches. 



Extent. From 2nd lumbar vertebra, where it commences 

 by a dilatation, the receptaculum chyli, to junction of left 

 internal jugular with left subclavian vein. 

 - Relations. The abdominal part is placed on the front of 

 the body of the 2nd lumbar vertebra, behind and to the right 

 side of the aorta and on the inner side of the right crus ; it 

 then enters the thorax through aortic opening, on the right
