山羊门静脉系统和肝静脉系统

THE PORTAL VENOUS SYSTEM AND THE HEPATIC VENOUS SYSTEM OF GOAT

用铸型法观察山羊肝的门静脉系统和肝静脉系统，发现门静脉的分支与人、猪、兔相似。中裂将山羊肝分为左、右两叶，左叶包括左外、内侧叶，右叶包括右外、内侧叶，尾状叶分别隶属于左、右叶。通过对多种动物肝叶愈合的比较，指出肝脏形态的种间差别主要表现在肝叶愈合程度不一，但肝叶愈合并无进化意义。

The portal venous system and the bepatic venous system were observed by cast technique. The branches of the portal vein of goat are similar to those of man,pig and rabbit.The liver of goat can be divided into the left lobe and right lobe by the fissura mediana. The left lobe includes the left lateral lobe and the left medial lobe,and the right lobe includes the right lateral lobe and the right medial lobe. The parts of the caudate lobe can be grouped into the left lobe and the right lobe resepectively.By comparing with some other animals on the fusion of lobes the author pointed out that the interspecific differences on the form of livers are mainly expressed in varying degrees of the fusion,but the fusion is not concerned with the evolution.
