In the photo above, you can clearly see my arm, wrist, hand, and fingers. Covering all of my bones and internal tissue is my Epithelial Tissue. This tissue is composed of cells that are closely packed together and can be in multiple layers. It covers the whole body in order to protect internal organs/tissues. Regardless of the type,epithelial tissue is generally separated from the underlying tissue by a thin sheet of connective tissue, which provides structural support for the epithelium.
