Epithelium Tissue Diagram
Structure of Epithelial Tissue Epithelial tissue is formed from a tightly fitted continuous layer of cells. One surface of the epithelial tissue is exposed to either the external environment or the body fluid. The other surface is attached to tissue by a membrane, which consists of fibres and polysaccharides secreted by epithelial cells.
Simple Columnar Epithelium: A Labeled Diagram and Functions Epithelium is a tissue that lines the internal surface of the body, as well as the internal organs. Simple epithelium is one of the types of epithelium that is divided into simple columnar epithelium, simple squamous epithelium, and simple cuboidal epithelium.
It supports the overlying epithelia, provides a surface along which epithelial cells migrate across during growth and wound healing, and it acts as a physical barrier (to malignant melanoma) Secreted by the epithelial cells.
