Simple columnar epithelium
Simple columnar epithelium lines the intestine, as seen here in the duodenum. Also visible is a brush border, composed of closely packed microvilli, which are commonly present on simple columnar epithelia. Interspersed between the cells are unicellular glands called goblet cells which secrete mucus. The mucus is released onto the epithelial surface. Small intestine 300x
