Simple columnar epithelium
Simple columnar epithelium can line ducts as they become larger, as seen in these images of a kidney tubule (left) and a salivary gland duct (right). In the case of the salivary duct, the nuclei are displaced upwards to the center of the cell due to cytoplasmic structures in the basal regions of the cell. Kidney, Submandibular gland 400x.
