The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body, lines body cavities and hollow organs and is the major tissue in glands. Epithelial tissue has a variety of functions depending on where it’s located in your body, including protection, secretion and absorption.

The organs in your body are composed of four basic types of tissue, including:

Epithelial.
Connective.
Muscular.
Nervous.
All substances that enter or leave an organ must cross the epithelial tissue first.

You have many different kinds of epithelial tissue throughout your body. Some examples of epithelial tissue include:

The outer layer of your skin (epidermis).
The lining of your intestines.
The lining of your respiratory tract.
The lining of your abdominal cavity.
Your sweat glands.
