. Cunningham's Text-book of anatomy. Anatomy. _ Central vein Central vein Sublobular vein Fig 940.—Liver of a Pig injected from the Hepatic Vein by T. A. Carter. (From a specimen left in the Anatomical Department of Edinburgh University by Sir William Turner.) Liver lobules of delicate fibrous tissue, which is most evident where the serous coat is absent. In the neighbourhood of the porta hepatis it is particularly abundant, and here it surrounds the vessels entering the porta, and accompanies them through the portal canals in the liver substance. This coat is continuous with the fine areolar tissue which pervades the liver, sur- rounding its lobules and holding them together. The liver substance proper is made up of an enormous number of small lobules -^gth. to Tyth inch (1 to 2 mm.) in diameter, closely packed, and held together by a small amount of con- nective tissue. In man the lobules are not completely separated from one another all round their circumference, but coalesce in places; the reverse is the case in certain animals such as the camel and the pig. The lobules are arranged around the branches of the hepatic veins, to form the compact mass of the liver, in the following manner:— The hepatic veins radiate from the inferior vena cava, at the posterior surface of the liver, to all parts of the organ, dividing and re-dividing until the vessels are reduced to branches of. Vena cava. Fig. 941.—Diagrams illustrating the Structure of the Liver.
