What is a characteristic of stratified columnar tissue?

Stratified columnar tissue is characterized primarily by its ability to protect underlying tissues. This type of tissue consists of multiple layers of columnar cells, which offer a robust barrier. The multiple layers serve as an effective protective mechanism against physical and chemical injuries, as well as microbial invasion. This is particularly significant in areas where abrasion or irritation may occur, such as the lining of certain ducts and the conjunctiva of the eye.

While stratified columnar epithelium can also be involved in secretion, its primary function centers around protection. The other characteristics, such as absorption and typical location in the respiratory tract, do not accurately describe stratified columnar tissue. In general, stratified epithelia are more commonly involved in protective functions rather than roles like absorption or secretion, which are better associated with simpler epithelial structures.
