With an altered manner of life, the unusual contents soon disappear again. In the lobule (Fig. 141) the cells lie crowded together in a radiated manner, forming simple rows. Reticular combinations gradually become more frequent externally. These are the so-called cellular trabecular and cellulo- trabecular reticula of our organ. Between the lobules we meet with in- terstitial connective tissue, sometimes only slightly developed (man), sometimes This connective tissue derives its origin, in part, from the investing membrane of the liver ; it is, in part, the continuation of a connective-tissue sheath which sur- rounds the blood-vessels and biliary passages entering the porta hepatis (Glisson's capsule). The liver receives its blood from two unequally developed supply tubes, the wide portal vein and the narrow hepatic artery. The first forms, around the lobules, partly shorter or longer branches (Fig. 94), sometimes, however, nearly and actually assuming a ring-shaped arrangement (pig). These branches rapidly divide into the compact capillary net-work of to mm. wide tubes. They approach the cen- tre of the lobule in a radial manner to bury themselves in the commencing portion of the hepatic vein, which is situated at this point. The latter, like its larger trunks, has uncom- monly thin walls, and has coalesced externally with the parenchyma of the liver. The branches of the hepatic artery, running along with the portal vein and biliary ducts, form, in the first place, nu- tritious vessels for both the last mentioned parts, and then capsular capillaries ; finally, they penetrate the lobule itself. They either bury themselves here in the branches of the por- tal vein, or pass over into the peripheral portion of the capil- lary net-work. Both varieties of net-work,
