Examination shows that the heart of andrias davidianus have three chamers - two atria and one ventride , the atria on the left of midline , the ventricle on the right of midline , and the atria are divided into two cavities by septum interatriale . there are four valvula semilunaris in conus arteriosus , but no spiral valve in conus arteriosus . the coronary artery is made by arterica carotis externa branches 研究结果表明,中国大鲵循环系统解剖学特点为： 1 .心脏：心房心室为左右排列，两心房前后排列，共有4对动脉弓，其中第二、三对动脉弓汇合成一条背主动脉；动脉圆锥基部与心室相接处有4个瓣膜，动脉圆锥内没有螺旋瓣，动脉圆锥与腹侧主动脉干之间有3个半月瓣；房间隔有穿孔；冠状动脉由颈外动脉的分支汇合而成。
