Detailed explanation-1: -The pseudostratified columnar epithelium secretes mucus in the vas deferens to help in the movement of the sperm. The pseudostratified columnar epithelium that contains stereocilia also helps in the absorption of excess mucus so that the sperms can become concentrated before their ejaculation.

Detailed explanation-2: -When food is swallowed, the multiple cell layers in the stratified epithelium help protect the underlying tissues from damage caused by food moving through the passageway.

Detailed explanation-3: -Stratified columnar epithelium is made up of multiple layers of epithelial cells. Often, it can be found between squamous epithelia and simple columnar epithelia. It has multiple layers of cells wherein the apical layer is composed of columnar cells and the deeper layer can be columnar or cuboidal.
