Stomach of snail to show lining epithelial cells. Light micrograph (LM). In most species the snail's stomach is a simple blind sac, in which the digestion by saliva continues. The main part of digestion takes place in the main digestive gland, a specialised gland taking most of the place in the visceral sac. It is also called a hepatopancreas, being both liver and pancreas. While usually the liver only produces digestive fluids and stores nutrients, in a snail's hepatopancreas digestion also takes place.
