Epithelia are not vascularized capillaries don't directly reach their cells the epithelium exchanges substances by diffusion with the connective tissue situated under it.

Since the epithelia are not vascularized minuscule scratches or skin injuries that happen all the time do not trigger bleeding and do not expose the blood to contamination from external agents this is an important protective strategy discovered by evolution.
