Question

What is the function of squamous epithelial cells in the lungs?

Answer 1

Hint: The cells that makeup body surfaces and line hollow organs are known as epithelial cells. For example, the small intestine, glomeruli in kidneys. These cells are located just below the epidermis that is responsible for absorbing nutrients.

Complete answer:
Squamous cells are epithelial cells that are thin and flat and are a type of epithelial cell. They can be simple (one layer) or stratified (multiple layers) (multiple layers). Gas exchange is heavily mediated by simple squamous epithelium. The walls of the alveoli in the lungs are made up of simple squamous epithelial cells that allow oxygen to diffuse quickly out of the lungs and into the bloodstream, where it can be transported to the rest of the body. Filtration is also carried out by simple squamous cells. The lung's epithelial cells are found at the interface between the environment and the organism and perform a variety of important functions, including barrier defense, fluid balancing, particulate removal, immune response initiation, mucus and surfactant development, and injury repair.

Note:
The stratification of squamous cells is usually a defensive step taken by the body. Since the stratified version of the tissue is solid and prevents abrasion, this is normal in the skin (epidermis) and the esophagus. However, the epidermis has a keratin coating on the outermost portion for extra strength and to indicate that the bulk of the epidermis is dead tissue (e.g., stratum corneum). The same tissue is found in the esophagus, but it is non-keratinized.
