摘要(Abstract)：

本文对东方对虾消化道及肝胰脏进行大体解剖和组织学观察,并将其结构与功能同其它主要十足动物作比较。 前肠和后肠内壁有几丁质层覆盖,中肠则没有。食道壁向四个角落内褶,在其表皮层之下的结缔组织中充满皮肤腺,环肌层连续,纵肌成束分散排列:胃的组织学结构除没有皮肤腺分布外,大体与食道相似。中肠从胸部延伸到第六腹节前区,约占消化道总长的60％,其上皮是一层柱状细胞,环肌层薄,纵肌成束分散排列;中肠前,后盲囊分别从中肠的前端和后端发出。后肠是一短管,内壁突出四个大的垫状隆脊,肛门开口于尾节腹面,和食道一样后肠壁分布大量皮肤腺:后肠上皮由单层柱状细胞组成,环肌层连续,纵肌在后肠前段成束分散排列于环肌之下,在后段则在环肌层之上。肝胰脏由许多分支肝小管构成,肝小管内壁为单层柱状上皮,中央为管腔:肝管细胞分为分泌细胞、吸收细胞、纤维细胞和原始细胞四种。原始细胞是一种未分化的细胞,分布于肝小管末端。
