Epithelial tissue

Epithelial tissue separates our body from the world we live in (outside environment) and it lines organs in our body. We have two types of tissues – depending on the number of layers (its look or, if you like, shape of the tissue):

Simple epithelial tissue – that type of tissues can further be divided into: squamous, cuboidal, cylindrical and pseudo-stratified tissues. Simple tissues develop in places where substances move intensely, e.g. in the processes of diffusion and absorption.

Stratified epithelial tissue – there is one type only – squamous tissues.

And now the elements common to both types of epithelial tissues – functions and features. They are present in each epithelium, no matter how many layers it has.
