In its fundamental arrangement the liver corresponds to a modified tubulargland, the system of excretory ducts of which is an outgrowth from the primarygut-tul)e. Early in fcetal life, however, the terminal divisions of the tubules uniteto form net-w orks, after which the tubular character of the liver becomes progressively Fig. 1444.

Branches of portal vein are purple; of hepatic artery, red ; of bile-ducts, yellow. Intralobularbile-capillaries are black. more masked by the intergrowth of the cell-cords and the large veins. Amongsome of the lower vertebrates, as in certain vermiform fishes or cyclostomes(A/vxtne), the primary tubular arrangement is retained. The glandular tissue composing the liver is subdivided into small cylindricalmasses, the lobules^ by the connective tissue which, in continuation of the fibrous STRUCTURE OP THE LI\ER. 1713 envelope, or capsitlc, investinj^ the exterior, at the transverse fissure enters theort;an and accompanies the interlobuhir vessels in their ramifications as the capsuleof (i/isson (capsiila fib
