Textbook Question In adults, more than 90% of all cancers arise from the epithelium. If such tumors arise in the epithelium of the glands, they are called carcinomas or adenomas (adenocarcinoma). In fact, skin, lung, colon, breast, and prostate cancers fall into these categories. Why do you think this is so? 110 views There is a video solution. What is Epithelial Tissue:  It is the thin tissue that covers all exposed sides of the body. They form the alimentary tract, outer skin, secretory glands, inner lining of the mouth, lining of the hollow parts of every organ such as the lungs, heart, eyes, ear, bladder, and the ventricular system of the brain. and the central canals of the spinal cord.

The cells that make up the epithelium are usually held together by a special structure called a tight junction. They are free from nerves and blood vessels; And they are supported by connective tissues called basement membranes.

Epithelial tissue performs many functions including abrasion, radiation damage, chemical stress and invasion by pathogens. A single organ consists of different types of epithelial tissue.

Protective tissue is thick and made up of many layers of cells and contains keratin-like inclusions to provide mechanical strength and resistance. For the most part, the skin of all mammals consists of a thick layer of keratinized dead epithelial cells. The esophagus is exposed to a wide range of different textures, pH levels and chemical composition, it also has a protective epithelium.

In contrast, epithelial tissues can also function in the absorption, secretion, and movement of substances. These tissues are thin in appearance and often consist of cilia or microvilli and consist of a single layer of cells.

What Is A Function Of Epithelial Tissue

There are different types of epithelial tissue, depending on the specific location. On the basis of cell layer, simple types of epithelial tissue:

Introduction To Epithelial Tissue Video Tutorial & Practice

Epithelia that are made up of a single layer of cells are called simple epithelial tissues. Epithelia consisting of two or more cell layers are called stratified epithelia.

Simple epithelium consists of a single layer of cells in direct contact with the basement membrane with a common apical surface. These cells can be cuboidal, squamous or columnar.

Simple squamous epithelium is located in the alveoli of the lungs and is important for the exchange of gases between the lungs and blood. Simple cuboidal epithelium lines the lumen of the collecting ducts of the kidneys and is found in the thyroid around follicles that secrete thyroid hormones. Simple columnar epithelium is present in the female reproductive tract and digestive tract. These cells are ciliated in the fallopian tubes and are involved in the movement of the egg towards the uterus. In the digestive tract, they are not ciliated and consist of microvilli that give a brush border appearance.

Stratified epithelium contains more than one layer of cells and only one layer of cells is in direct contact with the basement membrane. One layer of cells has the lumen of the organ or the apical surface exposed to the external environment. Several layers of these tissue cells protect against friction or abrasion. This tissue is located in the skin, and many dead keratinized cells provide protection.

Epithelial tissue separates two structures from each other. This is achieved by the tight junction between two epithelial cells. The tight junction inside the cells is also called the block junction because it prevents the flow of substances. These are formed by close interactions between two sets of extracellular domains.

Epithelial tissue has a structure called the basement membrane. It contains two parts; Beneath the basal lamina and reticular connective tissue. The basal lamina is composed of proteins, glycoproteins and collagen secreted by the epithelial tissue cells themselves. The basement membrane is important for nutrient transport, waste removal, and nerve signal transmission. It also plays an important role in anchoring the epithelium to the underlying connective tissue.

Simple squamous epithelium is located in the alveoli of the lungs and is important for the exchange of gases between the lungs and blood.

Stratified epithelium contains more than one layer of cells and only one layer of cells in direct contact with the basement membrane. Epithelial tissue or epithelium (plural = epithelium) is a protective, continuous sheet of tightly packed cells. Epithelium covers all internal and external surfaces of our body and lines body cavities and hollow organs. Epithelium also forms the main tissue of all glands.

Epithelial Tissue: What Is It, Where It’s Found, And More

[In this image] Epithelium is one of the four basic animal tissue types, along with connective tissue, muscle tissue, and nervous tissue.

The function of the epithelium varies depending on where it is located in your body. Examples include protection, secretion, sensing, and absorption.

Epithelial tissue is made up of a tightly packed continuous layer of epithelial cells. Between the epithelial cells is a small amount of intracellular material or matrix. Instead, epithelial cells are very close together, leaving no space between neighbors. Epithelial tissue has high cellularity (epithelial tissue is mainly composed of cells).

In contrast, cells in connective tissue are separated from each other and embedded in a matrix. Thus, the connective tissue is less cellular.

[In this image] Epithelial tissue is a tightly packed sheet of cells, with epithelial cells tightly adhered to each other. These cell sheets may consist of only one cell layer or a stack of multilayered cells.

In order to maintain the integrity of the epithelial barrier, the epithelial cells have a cube or cube shape. As we know a cube has six faces or sides; Each face of an epithelial cell is different. This intrinsic asymmetry observed in cells is called cell polarity.

The apical face of the epithelial tissue is exposed to the external environment or body fluid. Lateral faces are the four sides closely connected to neighboring cells by intercellular junctions. The basal facet is attached to the underlying connective tissue by the underlying membrane. The basement

What Is A Function Of Epithelial Tissue

The basement membrane separates the epithelium from the underlying connective tissue. The basement membrane can be further divided into two parts. The basal lamina (closer to the epithelium) consists of fibers and polysaccharides secreted by epithelial cells. The reticular lamina (closer to the connective tissue) is rich in collagen proteins produced by cells of the connective tissue, also known as fibroblasts.

[In this image] Most epithelial cells are separated from the connective tissue by a sheet of extracellular material called the basement membrane. It is made up of two layers: basal lamina and reticular lamina.

Blood vessels do not grow into the epithelial tissue, so it is called avascular. Instead, epithelial cells obtain nutrients from the capillaries of the underlying connective tissue. The exchange of chemicals between epithelium and connective tissue is done by diffusion.

Blood vessels do not penetrate epithelial tissue, but nerve endings do; That is epithelia
