If the respiratory membrane is composed of two layers of
stratified squamous epithelium, it will mostly contain numerous cell layers
because it is its composition of having to be a stratified squamous epithelium.
Another thing, the tissue will most likely be a shield for this type of
epithelium will serve as a protection against abrasion of which the respiratory
membrane will be protected of.
