Intestine absorbs the digested food materials. What type of epithelial cells is responsible for that ?
Intestine absorbs the digested food materials. What type of epithelial cells is responsible for that ?
The correct option is B Columnar epithelium
The correct option is B
Explanation of correct option:
- In the whole digestion process, the intestine plays a very crucial role in the absorption of digested food and facilitates it into the blood vessels.
- The columnar epithelium is situated in the digestive tract of the stomach, small intestine, and colon.
- Columnar epithelium cells are responsible for the absorption of the digested food materials.
- The small intestine acts as a protective barrier to bacteria and other microbes/pathogens but permits the absorption of digested food materials.
Explanation of incorrect options:
Option A
Stratified squamous epithelium cells are found in parts of the body where constant abrasion takes place, eg., the outer layer of skin, inner lining of the mouth, esophagus, and vagina. They do not responsible for the absorption process.
Option C
Spindle fibers are protein structures that arise from centrioles in a cell during mitosis.
Option D
Cuboidal epithelium is located in the kidney, glandular ducts, ovaries, and the thyroid gland (functions in protection, secretion, and absorption.
Final Answer: Columnar epithelium is responsible for absorbing digested food materials.
