Epithelial tissue epithelial tissue is a sheet of cells that covers a body surface or lines a body cavity two forms occur in the human body: covering and lining epithelium– forms the outer layer of the skin lines open cavities of the digestive and respiratory systems covers the walls of organs of the closed ventral body cavity glandular epithelium– surrounds glands within the body.

Epithelial definition, any animal tissue that covers a surface, or lines a cavity or the like, and that, in addition, performs any of various secretory, transporting, or regulatory functions see more. The general characteristic of epithelial tissue is that the cells are closely packed together since they form the linings of organs and body cavities, they have at least one side that's not in contact with other cells they lack blood vessels and obtain nourishment through diffusion because they.
Cells make up all tissues, tissues make up organs, organs make up systems and systems make up organisms cells have different types that make up different tissues each has different characteristics, but the epithelium and connective tissues are commonly confused for each other. The term tissue is used to describe a group of cells found together in the body the cells within a tissue share a common embryonic origin microscopic observation reveals that the cells in a tissue share morphological features and are arranged in an orderly pattern that achieves the tissue’s functions. The epithelial tissues are formed by cells that cover the organ surfaces such as the surface of skin, the airways, the reproductive tract, and the inner lining of the digestive tractthe cells comprising an epithelial layer are linked via semi-permeable, tight junctions hence, this tissue provides a barrier between the external environment and the organ it covers. Lining all the external surfaces and internal cavities of an animal's body are continuous sheets of cells known as epithelium all materials entering or leaving the body must ultimately cross at least one layer of epithelial tissue.
