应用循环灌注和血管铸型技术对南方鲶循环系统的结构进行了研究 ,结果表明 :南方鲶鳃部动脉中入鳃动脉由鳃弓腹侧中部距前端约 1 / 3处入鳃 ,出鳃动脉在鳃弓的前 1 / 2到 2 / 3处分别由两条合并为一条 ;躯干部至尾部具特有的背上动脉和背上静脉 ;静脉系统中有两条肝门静脉 ,尾静脉分为 3支 ,左右两支形成肾门静脉 ,中间一分支形成左肝门静脉 .
The structure of the catfish circulatory system in the southern catfish was studied by means of perfusion and blood vessel casting technique. The results showed that the gill artery in the gill artery of the southern catfish was gill inserted into the gill from the ventral midpoint of the glenoid arch about 1 / In the arch of the first 1/2 to 2/3 were merged into two by the two; trunk to the tail with a unique dorsal artery and dorsal veins; venous system has two hepatic portal vein, the tail vein is divided into 3 Branch, left and right form of renal portal vein, the middle of a branch of the formation of left hepatic vein.
