Epithelial tissue

Epithelium - Wikipedia, the free encyclopedia

"Epithelial tissue is composed of tightly connected cells arranged in one or more layers. Epithelial tissues covers the whole surface of the body (it's your skin!) as well as lining all cavities and forming glands. Epithelial tissues as many functions including protection, sensation, diffusion, secretion, absorption and excretion." http://www.hartnell.edu/tutorials/biology/tissues.html

Epithelial Tissue. Epithelial tissue covers the body’s outer surface and lines the internal closed cavities (including blood vessels) and body tubes that communicate with the exterior (gastrointestinal, respiratory, and genitourinary tracts). Epithelium also forms the secretory portion of glands and their ducts. Origin and Characteristics Epithelial tissue is derived from all three embryonic layers. Most epithelia of the skin, mouth, nose, and anus are derived from the ectoderm. Linings of…

Epithelia tissue covers the body surfaces, lines body cavities, forms external and internal linings of many organs, and constitutes glands. It has many different forms for its many functions: protection, secretion, excretion, absorption, filtration, and sensation. Each type of epithelial tissue will be outlined in detail.

The epithelium is a type of tissue that covers internal and external surfaces of your body, lines body cavities and hollow organs and is the major tissue in glands.

Classification of epithelial tissue

Epithelial tissues serve many purposes such as protection, secretion, absorbs, and filters what goes through cavities. There are many types of epithelial tissues, such as the epidermis (which is the outer layer of the skin). Epithelial tissues protects the body from bacteria. The epithelial tissues actually removes dust that is ingested during respiration. WOW! Note worthy!
