| Abstract: | The digestive system of Venerupis philippinarum Adams et Reeve is studied with histological and histochemical methods. The tubules of digestive gland are made up of two kinds of cell: digestive cell and basophilic cell. The digestive cells show activity of proteinase, non specific esterase, lipase, acid phosphatase and alkaline phosphatase, which suggests that the cells are involved in intracellular digestion of food material. The basophilic cells contain abundant protein and RNA. The epithelium of the digestive tract consists of ciliated columnar cells and mucous cells. The base of the style sac is connected with the intestine. The ciliated columnar cells in the intestine show activity of proteinase, non specific esterase and alkaline phosphatase. |
