Abstract
    The present study investigates in vitro 14C D-glucose transfer across the digestive wall of the irregular echinoid, Echinocardium cordatum (Echinodermata). It aims to characterize absorption ability of the gastric caecum. The experimental device used was the Ussing chamber system. It consists of two compartments clamped together, sandwiching the digestive wall. This allows orientated measurements of radiolabelled nutrient flux through the digestive wall i.e., from the digestive lumen to the perivisceral coelomic cavity. Incorporation of 14C D-glucose by the digestive tube wall as well as the transmural flux and the total amount of 14C D-glucose transferred to the coelomic compartment were quantified. The results show 14C D-glucose incorporation in the digestive wall did not differ significantly in the stomach, the gastric caecum and the intestine whereas the amount of 14C D-glucose in the coelomic fluid was significantly higher in the intestine and in the gastric caecum than in the stomach. These observations indicate regional specialization of the digestive tube and suggest that the caecum like the intestine is an important site of nutrient absorption.
