Question

Which of the following provides the least resistance to diffusion?
A) simple columnar epithelium
B) simple cuboidal epithelium

D) stratified squamous epithelium

Accepted Answer

Simple squamous epithelium is a thin single layer of flattened cells that allows for the easy diffusion of molecules across the membrane. The other types of epithelium have thicker layers or irregular shapes that provide more resistance to diffusion.
