This is a tissue composed of two or more layers and the cells tend to be cuboidal. This type of tissue is found in the epidermis of the skin and the linings of the mouth‚ pharynx‚ esophagus and anus. The function of this tissue is to protect and secrete. Transitional epithelium is the next type of tissue and it varies in shape from cuboidal to squamous. It is located in the
