Question

Which tissue lines the small intestine and the stomach?
A) simple squamous epithelium
B) simple cuboidal epithelium
C) simple columnar epithelium
D) pseudostratified ciliated columnar epithelium
E) stratified squamous epithelium

Accepted Answer

Simple columnar epithelium lines the small intestine and the stomach. This tissue is characterized by tall, cylindrical cells with microvilli on their apical surfaces, which increase the surface area for absorption and secretion. This tissue also contains goblet cells, which secrete mucus to protect and lubricate the lining of the digestive tract.
