| Abstract | ||
| This study was an attempt for investigation the tissues that compeise the digestive system of the bat, comparing it with the same system in mammalian . the bat has been anatomized and the organs of digestive system was taken away they include: tongue ,esophagus ,stomach ,small intestine and large intestine. Where they have been studies histological. The result of microscopial investigation for the tissues of digestive system of bat showed that it consists of the same four layers like in mammalian digestive system and it is from inner to outer layers as following :mucosa layer which consist of epithelial tissue ,lamina propria and muscular mucosa ,second layer the submucosa third muscular externa and lastly the serosa or advantitia except some differences in the tissues of parts of this layers in some mammalian . in bat, the tongue consist of filiform papillae ,fungiform papillae ,circumvallate papillae and foliat papillae ,the esophagus consist of the four layers except the difference in the epithelial layer in mucosa that consist of stratified squamous epithelial tissue non keratinized , in muscular externa layer in bat consist of smooth muscular, the stomach consist of four portions or parts , they are cardiac part , pleuric part ,the fundus and body and it also consist of simple and compound stomach glands and consist of three types of glands , they are the stomach glands or fundus glands ,pyloric glands and cardiac glands ,in small intestine consist of villi but could not be recognizing the three parts of from each other in bat , but in other mammalian we can recognize three parts of it, they are duodenum , jejunum and ileum , lastly the large intestine consist of two parts ,they are colon and rectum and appendix is absent in bat , there is no other difference between it and other mammalian . | ||
