Estudios histológico e histoquímico del sistema digestivo de la almeja catarina Argopecten ventricosus (Sowerby, 1842)

Histological and histochemical study of the digestive system of Argopecten ventricosus (Sowerby, 1842) 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.
