| Resumo: | Histological and histochemical studies on the digestive system of Argopecten ventricosus (Sowerby, 1842) was carried out. Lips show a ciliated columnar epithelium with glycoproteins and acid and alkaline phosphatases, and α-D glucosidase activity. Esophagus and lips epitheliums are similar. Acid and alkaline phosphatases, α-D glucosidase and leucil aminopeptidase activities were detected. The epithelium of the stomach is ciliated and contains glands which secrete glycoproteins. Acid and alkaline phosphatases, α-D glucosidase, leucil aminopeptidase and amylase activities were found. The digestive gland is tubular, and several activities were detected in the tubules. |
