why is it important for the cells in the lungs and digestive tract to be simple instead of being stratified
Answers
Answer:
The six main types of epithelia are simple or stratified squamous, simple or stratified cuboidal, and simple or stratified columnar. Squamous cells are flat, cuboidal cells are cube-shaped, and columnar cells are long.
Simple columnar lines the alimentary canal from the stomach to the rectum, while stratified squamous cells line the mouth, oesophagus, and anus.
Mucus can be secreted by simple columnar epithelial cells, which covers and protects the surrounding surface from injury.
Squamous cells that have been stratified give protection against:
external sources of mechanical friction - rubbing and physical trauma
harm caused by chemicals - chemicals/compounds found in the environment and internally the epithelium lining is deteriorating
Extracellular matrix components such as type III collagen, elastin, and proteoglycans are produced by these cells, which serve to maintain the structural integrity of the lung.
