Name the functions of epithelial tissue.

Explanation

The functions of epithelial tissues are :
Protection: The compound epithelium is multilayered and gives protection to the underlying tissues against chemical and mechanical stresses. Eg: Stratified squamous epithelium which forms the dry epidermis of the skin.
b) Absorption and Secretion: The goblet cells found in the epithelial lining of the digestive tract in the stomach secrete the protective lubricating mucus. This epithelium helps in absorption and secretion.
c) Filtration: The squamous epithelium found in the glomeruli in the kidneys form a diffusion boundary and aids filtration.
(d) Sensory reception: The ciliated epithelium occurs in the inner lining of trachea (Wind Pipe). By ciliary movement they help to trap microbes and dust particles.
