ABDOMINAL CAVITY 367 



The inferior and posterior surfaces are each divided into 

 segments by a right and a left pair of fossae, which run 

 parallel with the sagittal plane. The pair of sagittal fossae, 

 which separate the lower and the posterior surfaces into right 

 and left lobes, are the fossa for the umbilical vein, on the 

 inferior surface, and the fossa for the ductus venosus, on the 

 posterior surface. The pair of sagittal fossae, which segment 

 the lower and posterior surfaces of the right lobe, are the 

 fossa for the gall-bladder on the lower surface, and the fossa 

 for the inferior vena cava, on the posterior surface.

T FlG. 171. The Inferior or Visceral Surface of the Livei 



The Inferior or Visceral Surface of the Liver looks down- 

 wards, backwards and to the left, and rests partly upon viscera 

 situated at a lower level in the abdomen and partly upon the 

 front of the lesser omentum. It is separated into a larger right 

 and a smaller left segment or lobe by the fossa for the umbilical 

 vein. On the inferior surface of the right lobe, close to its 

 posterior border and at its left extremity, is the porta hepatisQi 

 hilum of the liver, through which the hepatic artery and the 

 portal vein pass into the liver, and the hepatic ducts and the 

 lymph vessels pass out. It connects the posterior part of the
