Histological and histochemical techniques were used to study specifics of parenchyma and stroma in digestive gland of Cornu aspersum. The parenchyma had 28.8 digestive ducts/mm2 on average (CV = 11.2 %) round-to-oval, with average cross-section of 27700.9 µm2 (CV = 28.1 %). The duct area (79.8 % of parenchyma) and the area of inter-duct connective tissue (20.2 % of parenchyma) were in ratio 4 : 1. The gland completely lacked elastic fibers. The muscle elements between the ducts were of different shape and arrangement, on average 59.7 µm long (CV = 42.3 %) and 1.41 µm wide (CV = 63.2 %). The gland’s capsule was formed by three layers: epithelial, muscular, and the layer of collagen fibers. More than 60 % of the capsule’s thickness belonged to the muscular layer. The proportion of calcium cells in the digestive duct wall was 15.5 % (CV = 23.5 %). Cells of digestive ducts contained a lot of vacuoles with brown granules (336.8 per 1 mm2, CV = 36.1 %). The vacuole area was 2.2 % of all area of digestive gland (CV = 15.8 %). The uneven location of muscle elements and brown granules in the glandular parenchyma indicated the functional features of the individual parts of the digestive gland.
