The epithelial cells are aggregated polyhedral cells that lines most of the covering of internal and external surfaces of the body, this includes the cavities in the body and hallow organs.
Simple squamous epithelium- A layer of flattened cells that facilitates diffusion like the exchange of gas in the lungs in the alveoli.
Simple columnar epithelium- Layers of slender and long cells that lines the small intestine and gallbladder, functions in the covering and absorption of nutrients.
Transitional epithelium- Also known as urothelium, a type of stratified epithelium that expands in response to the volume it is holding.
