Which Type of Epithelium Lines the Stomach and Intestinal Tract

Question

Which type of epithelium lines the stomach and intestinal tract?
A)transitional
B)simple columnar
C)stratified squamous
D)simple cuboidal
E)pseudostratified ciliated

Accepted Answer

The stomach and intestinal tract require a specialized type of epithelium that can handle and absorb nutrients. The best choice for this is simple columnar epithelium because it has tall, cylindrical cells with microvilli that increase surface area for nutrient absorption. Transitional epithelium lines organs that need to stretch and change volume, such as the bladder. Stratified squamous epithelium is found in tissues that undergo high amounts of wear and tear, such as the skin. Simple cuboidal epithelium is found in glands and their ducts. Pseudostratified ciliated epithelium is found in the respiratory tract.
