HISTOLOGY.

Sinusoids. *~- J 



in their walls. The sublobular veins unite to form the hepatic tributaries 



of the vena cava 

 inferior. The path 

 of the blood through 

 the liver is then 

 briefly as follows : 

 portal vein, inter- 

 lobular veins, sinus- 

 oids, central veins, 

 sublobular veins, 

 hepatic veins, vena 

 cava inferior. The 

 hepatic artery 

 through capillaries 

 connects with the 

 interlobular veins 

 and with the sinus- 

 oids at the periph- 

 ery of the lobules. 

 Certain patholog- 

 ical conditions sug- 

 gest that the cells 

 near the center of 



the lobules are not as well nourished as those at the periphery. 



Hepatic cells. The hepatic cells are arranged in anastomosing tra-

Interlobu- 

 lar vein 



(branch of 

 portal).
