ABDOMEN 



Fossa Vence, Cava. The fossa for the inferior vena cava is 

 a deep groove placed on the right side of the caudate 

 lobe. It ascends almost perpendicularly, and sometimes 

 it is converted into a tunnel by a bridge of liver substance 

 which passes behind the vein from the one side to the other. 

 In its anterior wall the orifices of the divided hepatic veins 

 will be seen. 



The bare area of the posterior surface of the liver is 

 triangular in form, and lies to the right of the fossa for the

vena cava. It forms the greater part of the posterior surface 

 of the right lobe, and is bounded above and below by the 

 lines of reflection of the coronary ligament. For the most part 

 it is convex, and it is connected with the diaphragm by loose 

 areolar tissue, and some minute veins which unite the portal 

 vessels of the liver with the systemic vessels of the diaphragm ; 

 but close to the lower end of the fossa for the vena cava there 

 is a well marked depression, the suprarenal impression, which 

 lodges the upper part of the right suprarenal gland. 



Porta Hepatis (O.T. Transverse Fissure). The porta 

 hepatis, or hilum of the liver, is the cleft on the posterior part
