Epithelial Cells
Epithelial Cells are what make up the cellular layer known as Epitheila, often used to seperate body tissue to external environment found in:
- Skin
- Intestine lining
- Lungs
- Kidney
Cilia are often found on the Apical membrane (the membrane that is exposed to the lumen) these significantly increase surface area to aid absorbtion and can even in some organs are used as a brush boarder to prevent infection.
The structure of a layer of epithelia shows junctions between each cell known as 'tight' or 'leaky' junctions. File:C:\Users\Nicola\Documents\Julia Uni\nrm0401 285a i1.gif
