Epithelial tissues:
These tissues originate from the three embryonic strata, Ectoderm, Endoderm, and Mesoderm. These tissues are located in a layer of cells covering the outer surfaces or lining the internal surfaces. The primary function is to protect the surfaces covered and the surfaces that lining them, and what is specialized in other ways to perform other functions such as absorption and excretion and transfer of materials.
The epithelial tissue is generally composed of one or more cells, a basement membrane on which the cells are based and an intercellular substance that is very few.
Division of epithelial tissues
The epithelial tissues can be divided into two parts:
3 - depending on the number of layers of fabric.
3- Depending on the shape of the tissue cells.
