In animals outgrowths or ingrowths from these surfaces form structures consisting largely or entirely of cells derived from the surface epithelium. Epithelium in anatomy layer of cells closely bound to one another to form continuous sheets covering surfaces that may come into contact with foreign substances epithelium occurs in both plants and animals. Epithelial tissue covers the outside of the body and lines organs vessels blood and lymph and cavities epithelial cells form the thin layer of cells known as the endothelium which is contiguous with the inner tissue lining of organs such as the brain lungs skin and heart the free surface of epithelial tissue is usually exposed to fluid or the air while the.

Epithelial cells have two surfaces that differ in both structure and function. Structure of epithelial tissue. In animals outgrowths or ingrowths from these surfaces form structures consisting largely or entirely of cells derived from the surface epithelium. The cells in this tissue are tightly packed within a thin ecm.
