Dissections of liver lobules to show their arrangement. 



11 A group of sui-face lobules. Bile ducts and branches of the hepatic artery- 

 have been omitted. 



12 A group of lobules situated deep in the substance of the liver. On the 

 left is seen a large portal canal with bile duct, hepatic artery, and portal vein. 

 The branches of these vessels were worked out as far as possible. Undoubtedly 

 some of them were torn away in lifting off the lobules in dissecting, so that all 

 the branches ramifying over the surfaces of the lobules are not shown, p.v., 

 portal vein; s.v., sublobular (hepatic) vein; c.v., central (hepatic) vein; b.d., bile 

 duct; h.a., hepatic artery.
