Question

Stratified epithelium refers to________

Answer 1

Epithelial tissues are thin tissue of the body. They cover a number of muscular components like internal lining of mouth, digestive tract, secretory glands, lining of whole components of each organ such as heart, lungs, eyes, the urogenital tract, etc. The cells which shape epithelial tissue are carefully connected to every different thru a shape referred to as tight junctions.

Complete answer:
A Stratified squamous epithelial layer is a tissue formed via more than one layer of cells, resting on one another, on a basement membrane. This tissue is current all over the body. These cells are keratinized and non-keratinized based on the cytoskeletal shape current in cells. Epithelial cells are these cells that make up the physique floor and strains the whole organs (e.g., small intestine, glomeruli in kidneys). Squamous cells are one of the sorts of epithelial cells characterised as skinny and flat cells. There are two kinds of epithelial cells; easy shape (one layer) and stratified shape (multiple layers). Simple squamous epithelium is solely responsble about fuel exchange. For example, these are observed in the lungs, the partitions of the alveoli, and are composed of easy squamous epithelial cells, which permit speedy diffusion of oxygen to pass out of the lungs and enter into the blood so that it can be transported to the relaxation of the muscular parts. Simple squamous cells are additionally used in the method of filtration. If the squamous cells are in a stratified form, then it is a protecting measure taken by way of the body. This is frequent in the pores and skin (epidermis) and the oesophagus as the stratified model of the tissue is sturdy and resists abrasion. Thus, the essential feature of stratified squamous epithelial cells is to shield from abrasion.

Note:
The keratinized epithelium covers the entire surface of the body, such as the palm and sole of the foot. The non-keratinized epithelium types the lining of inner structures such as the partitions of the lungs and digestive system. It is additionally located in the reproductive components and respiratory tract.
