Function

Squamous

It is made up of thin, flat and irregular-shaped cells. It forms the delicate lining of cavities (mouth, oesophagus, nose, etc.) and blood vessels.

It protects the underlying parts of body from mechanical injury, entry of germs, chemicals and drying.

Cuboidal

It consists of cube-like cells. These are found in kidney tubules, thyroid vesicles and in glands.

It helps in absorption, secretion and excretion. It also provides mechanical support.

Columnar

It consists of cells which are taller than broader i.e. pillar-like. It forms the lining of stomach, small intestine and colon.

Its main function includes absorption and secretion.

Ciliated

They are cubical or columnar cells with cilia. These are found in sperm ducts and line the trachea, bronchi, kidney tubules and oviducts.

The rhythmic, concerted beating of the cilia moves solid particles in one direction through the ducts.

Glandular

The columnar epithelium is modified to form glands which secrete chemicals.

Its main function is secretion.
