Why is epithelium better suited for protecting the body's external surface than a mucosa consisting of a simple columnar epithelium would be?

The stratified squamous epithelium is composed of several layers. It is thick and well suited for its protective qualities and its surface cells are constantly being replaced. Simple columnar epithelium is just a single layer of closely packed cells. It lines the digestive tract from the stomach to the rectum. Therefore, the latter would not be best suited to protect your outside surface.

∙ 12y agoOne of the functions of the epithelium is covering and lining surfaces. This gives protection to the underlying tissues. The epithelium creates many layers of protection, whereas the mucosa does not.

Stratified squamous non-keratinized epithelium?
In a word; it is a Shield.Stratified squamous epithelium is constituded of primarily flat cells and is suited to lining a surface that is exposed to friction or abrasion regularly. It is usually a layer over the top of a base membrane and can be torn or broken and replaced before the membrane it it protecting is harmed.Straified squamous epithelium can be further categorised into either posessing of being devoid of keratin. Non keartinised straified squamous epithelium must be moisutised by an external source (other than keratin) usually a bodily fluid to prevent them from becoming dehydrated and dying.Non-Keratinised stratefied squamous epilelium can be found in the Cornias, inside of the mounth, Recum, Vagina etc.
The internal and external surfaces of the body are covered by?
The internal surfaces such as inside blood vessels and lymph nodes are covered by endothelium and the external surfaces are covered by epithelium. "Epithelial tissues line the cavities and surfaces of structures throughout the body, and also form many glands." (Wikipedia)
What is the difference between flesh and skin?
Skin is the external limiting tissue layer of an animal or human. Flesh is soft substance consisting of muscle and fat that is found between the skin and bones of an animal or human.
What major tissue lines body cavity and covers the body external surface?
Epithelial tissues line cavities and cover the body. They are different in their types as the ones that line cavities are covered with a watery fluid (serous). The outer covering is dry.
The tissue that lines the tube and spaces in an animal's body?
Epithelium tissue is the tissue that lines the body's internal (for instance the digestive system) and external (the skin) surfaces. Epithelium tissue is made up of cells that pack together tightly to form a barrier or wall. This makes them well-suited for forming a protective lining. It is one of the four primary tissue types in the human body. The other three are connective tissue, muscle tissue, and nerve tissue.
Why can't chlamydia live on your skin?
Chlamydia prefers to infect a type of tissue called columnar epithelium. This tissue is found in mucous membranes, but not on the external skin.
Why the epithelium is much better suited for the body's external surface than mucosa?
Mucus epithelium is very delicate. It can not protect your body from the rough external environment. You need the tough stratified squamous epithelium to protect you from the rough external environment.
What separates the internal environment of the body from the external environment?
Epithelium
What is the most external skin region called?
stratified squamous epithelium
What is an ectoparasite?
An ectoparasite (or external parasite) is a parasite which feeds with at least part of his body outside the host's surface (epithelium, for animals). An ectoparasite (or external parasite) is a parasite which feeds with at least part of his body outside the host's epithelium. An ectoparasite is a parasite which body is not entirely inside the host's epithelium.
What is free surface?
An epithelium always has on surface where the cells are exposed either to the external environment or to an internal passageway or cavity; this surface is called the free surface of the epithelium.

What is the function of stratified epithelium tissue?
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
What are facts about epithelial tissue?
sheet of tissue that covers or lines the external and internal body surfaces. The epithelium is closely packed, has little intercellular material, and is lacking in blood vessels. There are three characteristic types of epithelial cells: squamous, cuboidal, and columnar. Squamous epithelial cells are flat and often overlapping; they compose the outer layer of skin (epidermis) and line certain internal cavities, e.g., the mouth. Cuboidal epithelial cells are rounded and elastic and line such structures as the urinary bladder, where, by stretching and becoming flatter, they increase the organ's capacity to hold fluid. The cells of the columnar epithelium are long and thin; they are found as a single layer of secretory and absorptive cells in the gastrointestinal tract, and they form the ciliated lining of the respiratory tract. Embryologically, epithelium may be derived from any of the three germ layers, i.e., ectoderm, mesoderm, and endoderm, and may be classified accordingly as epithelium proper, mesothelium, and endothelium.
Tightly bound sheet of cells lining any external or internal surface in multicellular organisms?
epithelium
