Segment of an hepatic lobule. 



The liver is composed of a multitude of small lobules which are 

 not completely insulated, being confluent in a part of their extent. The 

 interlobular branches of the hepatic artery and of the portal vein ramify 

 between the lobules (the former probably transmit no blood directly to 

 the capillary network of the lobules) ; these vessels collectively are called 

 Vasa interlobularia. The hepatic veins commence in the center of each 

 lobule as intralobular or central veins, Vasa intralobular ia s. Venae centrales. 

 The Vasa inter- and intralobular ia are connected with each other by a 

 capillary network , in the interstices of which are the hepatic cells. 

 Between the hepatic cells are the commencements of the biliary vessels, 

 which unite to form the biliary ducts, Ductus biliarii; these biliary ducts 

 accompany the Vasa interlobularia.
