Why would it be detrimental if the digestive tract had stratified columnar epithelium instead of simple columnar epithelium? Why would it be detrimental if the digestive tract had stratified columnar epithelium instead of simple columnar epithelium?
A. Stratified columnar epithelium would be too thin to allow for enzymes to work properly in the digestive tract.
B. Stratified columnar epithelium would contain both microvilli and cilia which would impede the functions of the digestive tract.
C. Stratified columnar epithelium would contain too many goblets cells, causing mucus to build in the digestive tract beyond tolerable levels.
D. Stratified columnar epithelium would be too thick to allow diffusion of water and nutrients into the blood stream.

Epithelium morphology correlates with their function. Those who intervene in secretion or absorption processes are simple epitheliums. Cells high frequently reflect their secretor or absorptive activity degree. Epitheliums that transport substances are characterized for presenting cubic or columnar cells.

In stratified epithelium, the shape and size of the cells vary from one layer to the other. Stratification correlates with transepithelial impermeability and friction exposure. It protects against humidity loss end mechanic erosion.

The stratified columnar epithelium is present in liquid passage areas. As it characterizes for being impermeable, it does not allow diffusion of water and nutrients into the bloodstream.
