Goblet cells in the epithelium produce mucus that traps the dust and dirt that is taken into the windpipe through the mouth and nose. The long, finger-like cillia cells then sweep the mucus back up the windpipe to the throat where it can be swallowed and then destroyed in the stomach by the digestive juices and acids.
The epithelial tissues are categorized into simple epithelium (one layer of cells), stratified epithelium (multiple layers of cells), squamous epithelium (flat cells), cuboidal epithelium (cube-shaped cells), and columnar epithelium (elongated cells). Epithelial tissues can be further classified based on their specific cell shape and function, such as ciliated epithelium, glandular epithelium, or transitional epithelium.
The cilia cells waft dirt and germs away from the windpipe.
Another name for squamous epithelium is "pavement epithelium" because the cells are flat and resemble tiles on a floor.
This type of epithelium would be classified as stratified cuboidal epithelium. It consists of multiple layers of cells where the basal cells are cuboidal in shape, while the superficial cells are flat. Typically, this type of epithelium is found in ducts of certain glands and parts of the respiratory tract.
Simple epithelium is a single layer of cells that are involved in absorption, secretion, and filtration, while compound epithelium consists of multiple layers of cells and provides protection and support. Simple epithelium is found in areas where minimal protection is needed, while compound epithelium is typically present in areas that are subjected to more wear and tear.
Pseudostratified epithelium is a kind of skin cell that looks like it is many different cells layered upon one another, but is really a single layer of cells. It is located in the throat and in male genitalia.
The structure that filters the air inside the windpipe, or trachea, is primarily the ciliated epithelium, which is lined with tiny hair-like structures called cilia. These cilia help trap dust, allergens, and other particles, moving them upwards toward the throat where they can be swallowed or expelled. Additionally, mucus produced by goblet cells in the epithelium captures these particles, further aiding in the filtration process. This helps ensure that the air reaching the lungs is cleaner and more suitable for respiration.
The ciliated columnar epithelium lines the trachea(windpipe) and bronchi(lungs). The squamous epithelium forms the delicate lining of cavities(nose and alveoli etc.)

The cilia cells waft dirt and germs away from the windpipe.
Epithelium made up of cells that produce secretions.
No. The term squamous means flat like a floor tile. Epithelium means a covering or lining with a free edge. Renal epithelium is simple epithelium and these cells are like cubes.
Epithelium Cells are usually flat and cover the surface of organs. There is a special type of epithelial cell. Millions of epithelical cells line our windpipe and help stop dust travelling all the way into our lungs. Once the dust has been stopped, they also push it back up the windpipe to the throat.
No, cells of the esophageal epithelium are not ciliated. The esophagus is lined with stratified squamous epithelium, which lacks cilia. Cilia are more commonly found in respiratory epithelium to help move mucus and particles.
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.
Transitional epithelium contains cells that are flattened and cells that are cuboidal; hence the name "transitional". Stratified squamous is different from transitional epithelium since the shape of the individual cell is more hexagonal and contains flattened cells. Transitional epithelium have the capacity to stretch and flatten.
