What is the function of the stratified squamous epithelium?

Stratified squamous epithelium is a type of tissue found covering and lining parts of the body. In this tissue, cells are flattened, joined tightly together, and stacked. The major function of this tissue type is protection, as it is found in areas that undergo wear-and-tear.
A.

What organs have stratified squamous epithelium?

Table of epithelia of human organs
SystemTissueEpithelium
digestiveoesophagusStratified squamous, non-keratinized
digestivestomachSimple columnar, non-ciliated
digestivesmall intestineSimple columnar, non-ciliated
digestivelarge intestineSimple columnar, non-ciliated
  • What cells make up alveoli?

    The fluid coating is produced by the body in order to facilitate the transfer of gases between blood and alveolar air. The surfactant is produced by the type II cells which are the most numerous cells in the alveoli, yet do not cover as much surface area as the squamous alveolar cells (a squamous epithelium).
  • Where are stratified cuboidal cells found in the body?

    This type of tissue can be observed in sweat glands, mammary glands, circumanal glands, and salivary glands. They protect areas such as the ducts of sweat glands, mammary glands, and salivary glands.
  • What is the function of the Pseudostratified columnar epithelium?

    Ciliated pseudostratified columnar epithelium cells are found in places such as the trachea and upper respiratory tract, where their cilia and mucous secretions help collect foreign materials so you can cough or sneeze them out.
B.

Where are squamous epithelial cells found in the body?

Simple squamous epithelia are found in capillaries, alveoli, glomeruli, outer layer of skin and other tissues where rapid diffusion is required. Cells are flat with flattened and oblong nuclei. It is also called pavement epithelium due to its tile-like appearance.
  • What does it mean to have squamous epithelial cells in urine?

    In healthy individuals, epithelial cells from the bladder and external urethra are normally present in the urine in small amounts. The presence of squamous epithelial cells may indicate contamination of the urine specimen.
  • Where are squamous cells found in the body?

    In contrast, cuboid epithelial cells are square and columnar epithelial cells are rectangular. Squamous cells are found in a variety of different parts of the body. You can find squamous cells in the mouth, on the lips, and on the cervix. They are also seen in the middle layers of the skin.
  • What is the function of a squamous cell?

    Simple squamous epithelial cells in the kidney enable rapid filtration of the blood and diffusion of small molecules. This process allows the kidneys to remove waste products and excess water from the body in the urine.
C.

What are stratified cells?

A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.
  • Where do we find squamous epithelium?

    Simple squamous epithelia are found in capillaries, alveoli, glomeruli, outer layer of skin and other tissues where rapid diffusion is required. Cells are flat with flattened and oblong nuclei. It is also called pavement epithelium due to its tile-like appearance.
  • Why the esophagus is lined with a stratified squamous epithelium?

    The esophageal lining is protected by a stratified squamous epithelium. Because this epithelium is normally not exposed to dryness or to abrasion, it is non-keratinized. A well-developed muscularis provides peristaltic propulsion of food. (Even when upside down, the esophagus can push food and drink to the stomach.)
  • What is stratified in anatomy?

    stratified (definition) more than one layer of cells. pseudo-stratified (definition) tissue appears to be stratified, but all cells contact basement membrane so it is, in fact, simple. squamous (definition)
