Required information Biophoto Associates/Science Source Based on your answer to the previous question, which of the following seems most likely? Multiple Choice All epithelial cells are dead and therefore do not require oxygen or nutrients. Epidermal blood vessels provide skin cells with nutrients and oxygen. Oxygen and nutrients must be absorbed from the environment through the skin surface. Oxygen and nutrients must diffuse into the avascular epidermis from the nearby dermis. The living keratinocytes survive by absorbing the dead keratinocytes in the skin layers above them.
