Epithelial tissue: important in the formation of some glands
Epithelial Tissue (Epithelium) - What is
Also known as epithelium, epithelial tissue is one of four types of human body tissue. It is formed by juxtaposed cells (joined together).
Epithelial tissue has the following characteristics: lack of space between cells (juxtaposed cells), lack of vascularization and excellent capacity for cell renewal.
Its main function is to protect the body against the entry of microorganisms (viruses, bacteria, protozoa), chemicals and physical aggressions (cuts, bumps, scratches).
Where is it found?
Epithelial tissue is found on the outside of the body (cornea, epidermis) and on the inner surface of hollow organs such as the stomach, ear, lung, mouth, uterus, nose, bladder, etc.
In addition, it is responsible for the formation of certain glands (liver, salivary glands, pancreas, etc.).
