facial veins the two external jugular veins are 

 united by a cross branch, the transverse vein. 



6. The Internal Jugular Vein returns blood from 

 the brain. It runs parallel to the carotid artery, 

 internal to the external jugular vein and unites 

 with the external jugular vein just before it emp- 

 ties into the brachio-cephalic. 



7. The Subclavian Vein is the large vessel which 

 returns blood from the fore-leg, where it has 

 branches similar to those of the subclavian artery. 

 It unites with the external jugular vein to form 

 the brachio-cephalic vein. 



8. The Left Vertebral Vein returns blood from the 

 cranial cavity. It empties into the left brachio- 

 cephalic, between the entrance of the external 

 jugular and the union of the brachio-cephalic 

 veins.
