What are the Functions of Squamous Epithelial Cells?
The functions of squamous epithelial cells vary depending on their location and type:
- Protection: In the skin, stratified squamous epithelium provides a barrier against physical damage, pathogens, and dehydration. - Diffusion and Filtration: In the lungs, simple squamous epithelium allows for the efficient exchange of gases. In the kidneys, it facilitates filtration of blood to form urine. - Secretion: In blood vessels, the endothelium (simple squamous epithelium) plays a role in secreting substances that control vascular relaxation and contraction.
