| 摘 要： | 对大鳍刺鰟鮍的消化系统进行解剖观察,发现消化道可以分为口、口咽腔、食道、肠和肛门等5个功能区.口腔内有咽及鳃耙,鳃耙形成了对食物颗粒的屏障,面向食管保护鳃丝.短的食管起源于咽腔,终止于肠.肠发达,分前肠、中肠和后肠,肠终止于肛门.消化腺有肝和胰,胰弥散在肝中,与肝合称肝胰脏.

| Abstract: | The digestive system of the Acanthorhodeus macropterus could be divided into five functional sections including oral,oropharyngeal cavity,esophagus,intestine and anal based on dissection observation.There are pharyns and gill rakers in the oral.The gill rakers form a barrier to food and protect the gill filaments esophagus.The short esophagus originats the pharyns and ends at the intestines.Pangpi fish there is no stomach,the developed intestines is divided into the foemer sub-gut,midgut and hindgut.The intestinal ends at the anus,the digestive gland can be divided into pancreas and liver,pancreas dispersed in the liver. |
