The epithelium is composed of continuous sheets of cells that line interior surfaces and cover the body’s outside surface. It is a selective barrier between tissues and is frequently engaged in absorption or secretion.
It is categorized by the number of cell layers (simple or complex), the morphology of the surface cells (squamous, cuboidal, or columnar), and its specializations (cilia, keratin, or goblet cells).
