What are epithelial tissue examples?
Types of Epithelial Tissue
| Epithelial Tissue Cells | |
|---|---|
| Cells | Locations |
| Stratified cuboidal epithelium | Sweat glands, salivary glands, and mammary glands |
| Stratified columnar epithelium | The male urethra and the ducts of some glands. |
| Transitional epithelium | Lines the bladder, urethra and ureters |
Is heart epithelial tissue?
The epicardium includes a layer of simple squamous epithelium called the mesothelium and the underlying supportive connective tissue. The epicardium is the outermost layer surrounding the heart, and is comparable to the tunica adventitia of vessels.
What organs contain epithelial?
Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities. Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart.
Where are epithelial tissues found in the body?
Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.
Does epithelium have a nerve supply?
Epithelial tissues have a nerve supply, but they do not have a blood supply. Therefore, epithelia must be nourished by substances diffusing from vascular structures in the underlying tissue.
Is blood epithelial tissue?
All epithelia is usually separated from underlying tissues by an extracellular fibrous basement membrane. The lining of the mouth, lung alveoli and kidney tubules are all made of epithelial tissue. The lining of the blood and lymphatic vessels are of a specialised form of epithelium called endothelium.

What happens when something goes wrong with the epithelia?
However, when something goes wrong with the epithelia, it can cause problems ranging from infertility to cancer. Although there are different types of epithelial cells, they all share some basic structural elements. First, these cells are polarized.
How are epithelial cells not squished with other cells?
However, the cells do have one area of their surface that is not squished with other cells. This is the free surface that can be exposed to air or fluids. For nutrients to enter the epithelial cells, they must use diffusion or absorption. The epithelial cells do not have a blood supply like other cells in the human body.
How many types of columnar epithelial tissue are there?
Columnar epithelial tissue: consists of elongated cell involved in absorption of materials The number of cell layers and cell types together give rise to 6 different types of epithelial tissue. Additionally, there are pseudostratified epithelia and transitional epithelia.
