THE LIVER. 



683. 



At the whole periphery of the liver the interstitial connective 

 tissue is in connection with the peritoneal capsule. Besides, there 

 is also a slight amount of connective tissue said to accompany 

 the capillary blood-vessels within the lobule. 



The larger bile-ducts are composed of fibrous connective tis- 

 sue, in which numerous acinous or racemose mucous glands are 

 imbedded. These glands, especially in the larger vasa aber- 

 rantia, exhibit the currant-like shape, and are arranged in regu- 

 lar double rows along the longitudinal axes of the ducts. 



The gall-bladder, as well as the three largest bile-ducts, are 

 lined by a connective-tissue layer abundantly supplied with

blood-vessels forming ridges in the bladder. Next to this follows- 

 a layer of smooth muscle-fibers, which freely interlace, and the 

 outermost layer blends with the structure of the covering perito- 

 neum. The inner lining consists of columnar epithelia, which 

 are prolonged to form mucous glands (Luschka). 



The hepatic artery is, in comparison with the size of the organ it 

 supplies, a small vessel, entering the porta with the portal veins.
