So, think of parts of the body where stratified and simple epithelium line.The stomach and small intestine, for example, are lined with simple epithelial tissue, but the skin, vagina and oesophagus are composed of stratified epithelial tissue.So areas where there isn't a huge amount of movement required are lined with simple epithelium (the stomach just secretes substances and the small intestine absorbs and secretes; absorption is made easier by having just the one layer). But the skin, vagina and oesophagus have to deal with a lot mechanical stress and so simple epithelium wouldn't be suitable which is why so many layers are needed; hence they are composed of stratified epithelium.Stratifed epithelia are two or more cells thick and simple epitheium are one cell thick
The alveoli in the lungs are made of a wet wall that is one cell thick with a network of capillaries to facilitate gas exchange.
stratified squamous epithelium
Stratified epithelium is a type of epithelial tissue that consists of multiple layers of cells. It is found in areas that require protection from mechanical or chemical stress, such as the skin or the lining of the esophagus. The layers provide strength and durability to the tissue.
The surfactant, also they have only one layer of squamous epithelial tissue, they have no mucus membranes, grape like cluster, one single thick cell.
Capillaries are only one cell layer thick, which allows for the exchange of nutrients and gases between the blood and tissues. This thin structure promotes efficient diffusion and transport across the capillary walls.
Simple For example, simple cuboidal epithelium A layered version would be Stratified cuboidal epithelium
they are related to air sacs because they both use specialized epithelial tissue. This tissue is only one cell layer thick.
Epithelial cells are rapidly dividing, and are more exposed to carcinogens like UV radiations, and environmental toxins than other tissues in the body as epithelial cells line the surface of the body. Cells which reproduce frequently are more prone to become cancerous than other tissues.
No it is false. A thick one layer protects more protection.
Yes it will be warmer depending on how thick your thick layer is!
There are four categories: Squamous â?? Cells are flat. Cuboidal â?? Cells are boxlike, with same height as width. Columnar â?? The cells are taller than wide. Transitional epithelium â?? Cells can vary from full/balloon-like to flattened, according to the distention of the organ they line. The three classifications by cell layers are: Simple - one cell thickness; Stratified - by appearance of uppermost cells; Pseudostratified - columnar structure that appears stratified, but isn't, due to the crowding of adjacent cells.
