1. Branches of portal vein. 



2. Bile ducts. 



3. Hepatic veins. 



4. Branches of hepatic artery. 



5. Lymphatics. 



Hepatic cells ttjVo in. in diameter grouped in 



lobules. 

 Lobules h in. in diameter. 



Interlobular veins (be- 

 tween lobules). 

 Intralobular capillaries 



(within lobules).

(within lobules). 

 Sublobular veins (under 



lobules). 

 Hepatic veins — exit at 

 portalfissure,empty in- 

 to superior vena cava.

 Intralobular capillaries 



(within lobules). 

 Course bej^ond the in- 

 tralobular capillaries 

 same as that pursued 

 by blood from portal 

 vein. 

 Start in lobules, form 

 network, and run from 

 centre to periphery. 

 Act as drain-pipes. 

 Glisson's capsule encloses the whole of the
