Question

The small intestine involved in food absorption have _________on their surface

• A. Squamous epithelial cells
• B. Simple cuboidal epithelial cells
• C. Ciliated epithelium
• D. Simple columnar epithelium

Answer 1

The correct option is D Simple columnar epithelium

The entire luminal surface of the small intestine has villi, small projections of mucosa. The villi are lined with simple columnar epithelial cells, also called enterocytes. The cells are tall with middle to basal nuclei and have an apical brush border, also known as microvilli.
Ciliated columnar epithelium moves mucus and other substances via cilia and is found in the upper respiratory tract, the Fallopian tubes, the uterus, and the central part of the spinal cord
