This is called metaplasia.
Pseudostratified columnar epithelium is a single layer of cells that appear to be layered due to varying cell heights, while stratified columnar epithelium has multiple layers of cells. Pseudostratified columnar epithelium is found in the respiratory tract and functions in secretion and absorption, while stratified columnar epithelium is found in the male urethra and functions in protection.
There are 8 types; simple squamous, simple columnar, simple cuboidal, stratified squamous, stratified cuboidal, stratified columnar, pseudostratified columnar, and transitional.
The nasopharynx is lined with respiratory epithelium, which consists of pseudostratified ciliated columnar epithelial cells. These cells have cilia that help trap and move mucus and particles along the respiratory tract for removal.
pseudostratified columnar epithelium
Pseudostratified columnar epithelium and stratified columnar epithelium are considered rare epithelial tissues in the human body.
lines the ducts of some glands and portions of the male urethra
Pseudostratified ciliated columnar epithelium lines most of the respiratory tract. This type of epithelium helps to trap foreign particles and move them out of the respiratory system with the help of cilia.
Pseudostratified columnar ciliated epithelium with goblet cells.
Pseudostratified columnar epithelium can be found in the respiratory tract, specifically in the lining of the trachea and bronchi.
Epithelial Cells of the pulmonary surface, and the epithelial duct elements of Glands; Ciliary epithelium, esophageal, germinal {of Ovaries}, glandular and membranous; The Cornea, larynx, nasopharynx, small intestine, stomach, olfactory, and pigments of the Retina; and Central to All is the Lining Of Capillary Branches. As well, here are the rest: Pseudostratified, seminiferous, simple, simple columnar, simple cubical, simple cuboidal, simple squamous, stratified, stratified columnar, stratified cuboidal, stratified squamous, surface - of stomach - , and transitional.

Nervous tissue is not a true stratified tissue. It is composed of neurons and glial cells, and is classified as a specialized type of tissue rather than stratified based on cell layers.
