Answer:
Explanation:
In Herdmania, digestive system includes the alimentary canal and digestive glands. Lying in the atrial cavity inside the mantle is a large bag-like pharynx or branchial sac. The wall of the pharyx is fused to the mantle along the anterior and ventral sides, on account of this attachment the atrial cavity is divided into right and left halves which are, however, continuous dorsally.
