epithelial cells

Postby MIA6 » Sat Dec 30, 2006 2:54 pm

What is epithelial cells? Capillaries wall is made of single epithelial cells. It means it is made of single LAYER of epithelial cells? Is that epithlium the same as epithelial cells?
Thanks for replies.

Hello MIA6,

- Epithelial cells are the cells which compose the epithelial tissue.
- Capillaries are composed of a single layer of epithelial cells (this layer is called endothelium).
- When we talk about epithelium, we also refer to epithelial cells and epithelial tissue. So yes, epithelium is the same than epithelial tissue and the same than set of epithelial cells.

I hope I have answered your doubt...

Take a look to the figure:
