 the portal vein and the first part of the duodenum, the foramen epiploicum, and the 

 posterior surface of the liver. More superficially are coils of small intestine, the great

To its left side are the aorta and the right crus of the diaphragm. 



On its right side, below, is the right ureter, whilst at a higher level the right kidney 

 is separated from the vein by a short interval only.

 formed, and through which it receives blood from the pelvis and from the lower extremi- 

 ties, the inferior vena cava receives the following tributaries : The hepatic veins, the
