arise from the lower part of the plexuses, opposite the external orifice of the uterus, 

 and open into the corresponding hypogastric vein. 



The vaginal plexuses are placed at the sides of the vagina; they communicate 

 with the uterine, vesical, and hemorrhoidal plexuses, and are drained by the 

 vaginal veins, one on either side, into the hypogastric veins. 



The common iliac yeins (vv, iliacae 

 communes) are formed by the union 

 of the external iliac and hypogastric 

 veins, in front of the sacroiliac artic- 

 ulation; passing obliquely upward 

 toward the right side, they end upon 

 the fifth lumbar vertebra, by uniting 

 with each other at an acute angle to 

 form the inferior vena cava. The 

 right common iliac is shorter than 

 the left, nearly vertical in its di- 

 rection, and ascends behind and then 

 lateral to its corresponding artery. 

 The left common iliac, longer than 

 the right and more oblique in its 

 course, is at first situated on the medial side of the corresponding artery, and then 

 behind the right common iliac. Each common iliac receives the iliolumbar, and 

 sometimes the lateral sacral veins. The left receives, in addition, the middle sacral 

 vein. Xo valves are found in these veins. 



The Middle Sacral Veins (vv. sacrales mediales] accompany the corresponding 

 artery along the front of the sacrum, and join to form a single vein, which ends in 

 the left common iliac vein; sometimes in the angle of junction of the two iliac veins.

'ecufiarities. The left common iliac vein, instead of joining with the right in its usual posi- 

 tion, occasionally ascends on the left side of the aorta as high as the kidney, where, after receiving 

 the left renal vein, it crosses over the aorta, and then joins with the right vein to foim the vena 

 cava. In these cases, the two common iliacs are connected by a small communicating branch 

 at the spot where they are usually united. 



The inferior vena cava (v. cava inferior') (Fig. 577), returns to the heart the blood 

 from the parts below the diaphragm. It is formed by the junction of the two 

 common iliac veins, on the right side of the fifth lumbar vertebra. It ascends along
