they are flat cells. they can either be simple (one layer) or stratified (multiple layers)
simple squamous epithelium
The wall of the alveoli in the lungs is composed of simple squamous epithelium (also known as type I alveolar cells). These cells are thin and specialized for gas exchange, allowing oxygen to diffuse into the bloodstream and carbon dioxide to diffuse out.
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.
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.
The outermost layer of skin (epidermis) and the lining of blood vessels and alveoli in the lungs are good examples of squamous epithelium. These layers are characterized by flat, thin cells that form a protective barrier and allow for rapid diffusion of substances.
A single flattened layer of epithelial cells can represent squamous epithelium. Squamous epithelium is a type of epithelial tissue characterized by flat, scale-like cells that are closely packed together.
Another name for squamous epithelium is "pavement epithelium" because the cells are flat and resemble tiles on a floor.
Simple columnar epithelium cells will heal faster than stratified squamous cells. The stratified squamous cells rarely have contact with blood.

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.
Stratified squamous epithelium
Stratified squamous epithelium would heal faster compared to simple columnar epithelium because it consists of multiple layers of cells and has a greater capacity for replication and regeneration. This allows stratified squamous epithelium to replace damaged cells more quickly and promote faster healing.
No, simple squamous epithelium is thin and not well-suited for areas subject to abrasion. Stratified squamous epithelium, with multiple layers of cells, is better adapted to withstand abrasion and protect underlying tissues.

According to my histology textbook, non-keratinized stratified squamous epithelium lines the length of the Esophagus. not too sure why though!! when cells are not keratinised the surface cells can be used alternatively to protect the underlying cells. this only occurs in areas where there will be very little friction therefore damage caused to the cells. WHY its non-kerantinized, because its WET. keratinized stratified squamous epithelium is dry (nails, hair, skin).
