What are 5 examples of epithelial tissue?
The names are as follows:
- Lining of the small intestine – Columnar epithelium.
- The lining of the kidney tubules – Cuboidal epithelium.
- Lining of blood vessels – Squamous epithelium.
- Respiratory tract – Ciliated Epithelium.
What are the 5 epithelial tissue functions?
They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
What are the 5 general characteristics of epithelial tissue?
Despite there being many different types of epithelial tissue all epithelial tissue have just five characteristics, these are cellularity, polarity, attachment, vascularity, and regeneration. Cellularity as the name suggests means that the epithelium is made up almost entirely of cells.
What are the types of epithelial tissue?
There are three principal cell shapes associated with epithelial cells: squamous epithelium, cuboidal epithelium, and columnar epithelium. There are three ways of describing the layering of epithelium: simple, stratified, and pseudostratified.
What is the example of epithelial tissue?
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 epithelial tissue skin?
Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities. For example, the skin is composed of a layer of epithelial tissue (epidermis) that is supported by a layer of connective tissue. It protects the internal structures of the body from damage and dehydration.
Why are there different types of epithelial cells?
The cells of the tissue can take up different shapes to become specialized and perform specific functions. And so, epithelial tissues have cells that have different shapes, sizes, and arrangements. Accordingly, they are classified into different types.
Where are the epithelial tissues located in the body?
They are found in the salivary glands, kidney tubules, sweat glands, etc. Their main function includes absorption, secretion, and excretion. If the cuboidal epithelium is arranged in many layers it forms the stratified cuboidal epithelium. It is found on the inner side of the pancreatic ducts and salivary glands.
What are the functions of squamous epithelial cells?
You will see how their shape adapts according to the functions that they perform. Squamous Epithelium – These are thin, flat cells that are closely packed. The squamous epithelial cells line the cavities of the mouth, esophagus, alveoli, and blood vessels. This tissue gives protection against mechanical injury and also blocks the entry of germs.
Why are cells tightly packed together in epithelial tissue?
The cells in epithelial tissue are very closely packed together and joined with little space between them. With its tightly packed structure, we would expect epithelial tissue to serve some type of barrier and protective function and that is certainly the case.
