Simple columnar epithelium cells line the stomach. These cells also line the small intestine and the large intestine. They are uni-layered and are of two types - ciliated and non-ciliated.
Simple squamous epithilium
The jejunum is lined with simple columnar epithelium. This type of epithelium is specialized for absorption and secretion, making it well suited for the functions of this part of the small intestine.
The sublingual gland is composed of both mucous and serous acini. The mucous acini are lined with simple columnar epithelium, while the serous acini are lined with simple cuboidal epithelium.

The jejunum is lined with simple columnar epithelium. This type of epithelium is specialized for absorption and secretion, making it well suited for the functions of this part of the small intestine.
The kidney tubules are lined with simple cuboidal epithelium, which helps in reabsorption and secretion of substances. The ducts of salivary glands are lined with simple columnar or pseudostratified columnar epithelium to facilitate the transport of saliva. Both types of epithelium provide a barrier and aid in specific functions of these structures.
The sublingual gland is composed of both mucous and serous acini. The mucous acini are lined with simple columnar epithelium, while the serous acini are lined with simple cuboidal epithelium.

Through stratified squamous epithelium absorption will be very poor and person will die of starvation.Malabsorption could occur if the digestive tract were lined with stratified squamous epithelium instead of simple columnar eqithelium.
The duodenum is lined with simple columnar epithelium, which is specialized for absorption and secretion. This type of epithelium contains cells with microvilli that increase the surface area for nutrient absorption in the small intestine.
The trachea is lined with ciliated columnar epithelium, which has hundreds of tiny hairs called cilia.
The nasopharynx is lined with respiratory epithelium, which consists of pseudostratified ciliated columnar epithelial cells. These cells have cilia that help trap and move mucus and particles along the respiratory tract for removal.
The respiratory system is largely lined with pseudostratified ciliated columnar epithelium.
The small intestine is lined by simple columnar epithelium, which is NONCILIATED, which means it does not have Cilia on its surface. Instead it has Villis and Microvillis which help to absorb digested food
