Quizplus · Accepted Answer

Simple columnar epithelium is the type of tissue that lines the surface of the small intestine and much of the large intestine. This tissue is designed for absorption and secretion of digestive enzymes and other substances. Stratified squamous epithelium is not found in the GI tract. Simple squamous epithelium is found in areas involved in diffusion and filtration, such as the lungs and kidneys. Pseudostratified epithelium is primarily found in the respiratory tract.
