THE LIVER. l6l 



gall-capillaries. The gall-capillaries are extremely 

 narrow and form a delicate net-work around the 

 individual liver-cells ; being arranged in such a way, 

 however, that they never come into contact with 

 the blood-capillaries, always being separated by at 

 least a part of the diameter of a liver-cell from the 

 latter. They do not seem to possess a distinct wall, 

 but are rather simple channels grooved in the walls 

 of contiguous liver-cells. 



The connective tissue of the human liver is chiefly 

 found in the capsule which surrounds the organ, and 

 in the capsule of Glisson, which accompanies the 

 larger vessels ; but, in addition to this, we find it in 

 very small quantity, not only in the vicinity of the 

 hepatic vein, but also between the cells and along 

 the capillaries within the lobules ; in the latter situ- 

 ation it occurs in the form of delicate fibres or 

 membranes, with here and there fusiform or stellate 

 cells. 



The lymphatic vessels of the liver form an abun- 

 dant net-work in the capsule, and also accompany 

 the larger vascular trunks in Glisson's capsule and 

 between the lobules, and are connected with minute 

 intralobular lymph-spaces. Here and there in the 

 interstitial tissue of the liver are found small irregu- 

 lar nodules of lymphoid tissue, see page 135.
