| Abstract: | The digestive system of Solen gouldii Conrad was studied with histological and histochemical methods.The tubules of the digestive gland consist of the digestive and basophilic cells.The digestive cells contain many vesicles which have the acid phosphatase activity, it indicates that the cells are involved in intracellular digestion of food material.The columnar cells with dense microvilli of the ducts also have acid phosphatase activity.The digestive tract is lined with ciliated columnar cells and mucous cells. Subepithelial mucous cells are present in the esophagus,which secrete neutral and acid mucous materials. The epithelium of the stomach and the intestine present proteinase and non-specific esterase activity. Acid and alkaline phosphatase activity is also present in the epithelium of the intestine. |
