Thanks @nincompoop. Just did a revision. They are specialised, but not dead! lol sorry 'bout that.

Answer 4

~ give the animal body its form and shape. One important function of epithelia is therefore the mechanical protection of the underlying tissues.
~ transport of substances into or out of the animal body. All substances that enter or leave the animal body must cross an epithelium.
~essential for respiration, the exchange of gases across the body surface.
~support digestion through the secretion of salt, water, acid or base, hydrolytic enzymes and emulsifying bile salts
~important function of epithelia that line the digestive canal of animals is nutrient absorption.
~contribute to temperature regulation through the development of isolating layers of extracellular material and through the secretory activity of sweat glands
