Want this question answered?
The cells in the skin epithelium are cuboid, mostly dead, with very low vascularity and saturated with keratin which prevents not only gases from diffusing in and out of the body, but also prevents liquids and solutes from moving out of the body. There are, anyway, epithelia that allow oxygen flow, like the lung's epithelium, since epithelium is a kind of tissue that covers others, therefore, not only skin is epithelium.
depends on the type of epithelium. I'm assuming you are asking about stratified squamous epithelium as that is the most common type. It is found in areas of the body that are subjected to a lot of stress (environmental, mechanical) such as the skin, the anus, the oropharynx, and the vagina. Stratified columnar epithelium is found throughout the GI tract.
Epithelium. There are many kinds of Epithelium.
The secretory epithelium is a part of the skin and associated with the sweat glands.
Simple stratified epithelium lines the anus.
Simple For example, simple cuboidal epithelium A layered version would be Stratified cuboidal epithelium
stratum lucidum

Epithelium is found covering external or internal surfaces in the body. Stratified epithelium consists of more than one layer of cells. It is often found in situations subject to abrasion, where the top layers of cells are worn off. Layers underneath replace the lost cells, so the basic function of stratified epithelium is protection. See: http://ect.downstate.edu/courseware/histomanual/epithelia.html

The stratum lucidum is the clear layer of the skin. It is found only in the thick skin of the palms and soles.
The type of epithelial tissue that is found in the epidermis of the skin is called stratified squamous epithelium. The dermis consists of connective tissue.
Epithelium connective tissue muscle nerve and your skin! sorry but skin is actually epithelium tissue that's why i didnt write skin
The stratum lucidum, which is present in the thick skin of the palms and soles, is absent in thin skin
