Simple columnar epithelium.
A single layer of tall, thin columnar epithelial cells with oval-shaped nuclei situated in the basal area and connected to the basement membrane makes up simple columnar epithelium.
The majority of the human digestive tract's organs, including the stomach and intestines, are lined by simple columnar epithelium. Non-keratinized stratified squamous epithelium makes up the esophagus.
Keep in mind that connective tissue papillae have the ability to puncture the basal surface of the epithelium rather deeply.
