Simple columnar epithelium forms a lining of the stomach, small intestine, colon, gall bladder, gastric glands, intestinal gland, and pancreatic lobules. Since here it performs the secretory functions, it is called theglandular epithelium.Certain cells of the columnar epithelium of the stomach and intestine produce mucus which forms a fine mucus coating over the epithelium. These mucus-producing cells are calledgoblet cells.The epithelium having mucus-secreting cells along with underlying connective tissue is calledmucous membrane or mucosa.
