Which of the following epithelial types is correctly matched with its major function?
Correct answer
D
Rationale
The correct answer is D. Simple columnar epithelium is indeed primarily responsible for secretion and absorption due to its tall shape and presence of microvilli, which increase surface area for these functions. Simple squamous epithelium is mainly involved in diffusion, allowing for the exchange of gases or nutrients. Stratified squamous epithelium functions more for protection against mechanical stress and pathogens, as it forms a tough, protective barrier due to its many layers.
