    I chose all three answers.

    highly vascular
    too thick
    too dry

    Who the hell knows...

    I went with too thick and too dry. highly vascular would seem to help repiration if you were going to do it through the skin, right? Getting the O2 to the hemoglobin so that it could reach the tissue which weren't on the surface? That was my reasoning anyway!

  3. Dry is definitely the answer.
    Too thick depends on what it means: if it means thick keratinized epidermal, then yes.
    Vascularized is not the answer; any cell or tissue to be alive need be vascularized.

    i eliminated vascularized cuz i thought the epidermis is avascular (as opposed to the dermis). so i ended up with the other 2 choices. but who knows... i'm so bitter about this exam right now.
