摘　　要：解剖测量了 8只成年四眼斑龟的消化系统和呼吸系统 ,结果表明 :消化管总长 ( 6 0 4 3± 99.2 )mm ,为背甲长的 3 75～ 5 77倍。舌不能伸缩 ;食管扩展性强 ;胃呈囊状 ,被肝叶覆盖 ;小肠较长 ,为消化的主要场所 ,约占消化道总长的 4 8% ;盲肠不发达。肝较大 ,重约 ( 14 12± 8 2 4 )g ,分左、中、右三叶 ,占体重的 6 %左右 ,绿色胆囊位于右叶小肝内 ;胰腺长条形 ,分布于十二指肠肠系膜内。肺长囊形 ,内壁有复杂的间隔 ,把内腔分隔成蜂窝状小室 ,紧贴在背甲的内表面 ,位于肩带和腰带之间 ;气管较长 ,由 6 5～ 85个软骨环连接而成 ;支气管较短 ,由 30～ 4In this paper, eight adult Four Eye\|spotted Turtles were dissected. Th e results are as follows: the length of the whole digestive tract is 604 3±9 9 2 mm, 3 75-5 77 times as long as that of the carapace.
