605. The Branches of Origin of the Vena portae. 



The portal vein, Vena portae, receives its branches or roots of 

 origin from the digestive organs and carries their blood to the liver. 

 These roots unite to form the Truncus venae portae, which ramifies in 

 the liver. 



The branches of origin of the V. portae are : 



a) The superior gastric vein, which runs along the upper 

 curvature of the stomach from left to right, and receives the blood from 

 the upper portion of the stomach and superior transverse portion of the 

 duodenum. 



b) The s u p e r i o r or g r e a t m e s e n t e r i c vein, which receives 

 the blood from those portions of the intestine, which are supplied by 

 the superior mesenteric artery and the pancreatico-duodenal branch of 

 the hepatic artery.
