Abstract:To investigate digestive mechanism of Mactra chinensis Philippi, the digestive system is studied with histological and histochemistrical methods. The epithelium of the digestive tract consists of ciliated columnar cells and different amount of mucous cells. The ciliated columnar cells in the stomach and the intestine show activity of proteinase, lipase, non-specific esterase and alkaline phosphatase. The tubules of the digestive gland are made up of basophilic cells and digestive cells. The basophilic cells contain abundant protein and RNA. The digestive cells show activity of proteinase, lipase, non-specific esterase, alkaline phosphatase and acid phosphatase, suggesting that the cells are involved in intracellular digestion of food material.
Keywords:Mactra chinensis  digestive system  histology  histochemistry
