Epithelium - Wikipedia
Epithelium or epithelial tissue is a thin, continuous, protective layer of cells with little extracellular matrix. An example is the epidermis, the outermost layer of the skin. Epithelial (mesothelial) tissues line the outer surfaces of many internal organs, the corresponding inner surfaces of body cavities, and the inner surfaces of blood vessels.

The primary tissues protecting us from exterior insults are the epithelia of the skin, airways, and gastrointestinal (GI) tract. The epithelium not only acts as a physical barrier; it actively responds to stimuli such as allergens, pollution, or microbes by releasing epithelial-derived cytokines that initiate and drive type 2 immune responses.
