Is epithelium vascularized
Is epithelium vascularized? How do oxygen and nutrients reach the epithelium? Why is this characteristic an important evolutionary acquisition?
Expert
Epithelia are not vascularized (that is, capillaries do not directly accomplish their cells). The epithelium exchanges substances through diffusion with the connective tissue located under it. Since the epithelia are not vascularized minuscule skin wounds or scratches which take place all the time do not trigger bleeding and do not expose the blood to contamination from exterior agents. This is a significant protective strategy introduced by evolution.
