Anatomy & Physiology Question #26


The nurse is caring for a patient with a burn. Which should the nurse identify as the function of epithelial tissue?


  1. Control permeability of surfaces to anything that enters or leaves the body
    • Rationale:
  2. Provide protection
    • Rationale:
  3. Produce specialized secretions
    • Rationale:
  4. Cell specialized for absorption, secretion or to act as a barrier
    • Rationale:



The correct answers are B & C. Epithelial cells form very cohesive sheets of cells, called ‘epithelia’, which function mainly for covering, lining, and protecting surfaces of the body. Epithelial cells are specialized for absorption, secretion, or act as a barrier. The cells do not secrete or control permeability alone.The other answer choices do not address epithelial cells and burns.
