Abstract

The macro and micro anatomy of the salivary and digestive glands of Bellamya unicolor has been carried out in this paper. The structure of these glands and their ducts has been correlated to their functions. It has been found that the two salivary gland ducts pour their mucoid secretion into the buccal cavity. The two lobes of the diges tive gland consist of a number of tubules formed of secretory, digestive and excretory cells. The two common digestive gland ducts op < /strong>en into the distal limb of the cardiac stomach.
