5. Epithelial tissues are widespread throughout the body and are responsible for:  covering all body surfaces.body surfaces  lining body cavities and hollow organs.  form the major tissues in glands.  perform a variety of functions including:  Absorption  Filtration  Excretion  Secretion  Diffusion  Protection Main Menu
