Morphometric, Anatomical and histological features of Gastrointestinal Tract (GIT) of Freshwater Turtle, Pangshura tentoria

Abstract — The gastrointestinal tract (GIT) of reptiles draws our attention as numerousresearches in the field of biological science have been going on using reptile as a model animal. The GIT morphology and physiology elaborates the variety in food and feeding habits. The aim of present investigation is to study the morphometrical and histological features of gastrointestinal tract of freshwater turtle, Pangshura tento-ria. The oesophagus, stomach and intestine of Pangshura tentoria is buildup of fourlayers from outside inwards are serosa, muscularies, sub-mucosa and musoca. The oesophageal mucosa consists of simple columnar ciliated epithelial and goblet cells. The intestinal glands are ab-sent. There are no much differences between the length of oesophagus and Stomach but the small intestine is larger in case of female. The length of whole gastrointestinal tract is sex dependent. In conclusion, the characteristic variation of the gastrointestinal tract is related to their ecology and physiology
