| Abstract: | Digestive system of Asto otus were studied by dissection,measuration,paraffin sectioning and HE staining.The results showed that Asto otus had thick esophagus and had no crop.The mulous membrane layer was stratified squamous epithelium.The glands in stomach were well developed,which were composed of simple tubular glands and tubulocinar glands.The cutin film was not found in muscular stomach.The intestinal villis in duodenum were dense and long,but shorter and thicker in jejunum and ileum.The intestine glands were well developed in the whole small intestine.The muscle layer relied mainly on circular muscle.The caecum wall was thin and the rectum wall was thick.The boundary of liver lobule and pancreatic lobule was obscure. |
