ANATOMY or THE DOMESTIC FOWL 



The vertebral veins are divided into the anterior and the posterior, 

 or the inferior and the superior. The anterior vertebral vein is located 

 in the cervical region and collects the blood from the brain and the 

 inner part of the head. The vertebral vein passes along the dorsal 

 side of the spinal cord.

The posterior vertebral vein is located in the dorsal region, passes 

 backward and receives the blood from the dorsal neck region and 

 from the intercostal veins and from the vertebral segments and 

 adjacent regions. 



The anterior and the posterior vertebral vein form one trunk, 

 the vertebral vein, and this trunk empties into the vena jugularis 

 just before the subclavian and the jugular unite. 



The subclavian vein collects the blood from the anterior extremi- 

 ties. It unites with the vena jugularis of the same side. 



The left vena cava receives the coronary veins from the heart.
