Which of the the following is not a function of the dermis layer of the skin?
Uh... D.





Dead cells have nothing to do with the protection of anything. And if they did, how could they protect the epidermis if it lies underneath the dermis?
Which of the the following is not a function of the dermis layer of the skin?
D?
Reply:D is the answer. It's wrong because the epidermis is on top of the dermis. Don't be thrown off by the first part; the epidermis is made of 25 - 30 layers of dead skin (at least Wiki says so), but the rest of that choice is wrong.





A: true. I'm sure you've experienced sweating before.


B: true. Again, ever been burned or stuck with a needle?


C: yep. Although you shouldn't get too much UV, since that can lead to skin cancer.
Reply:I agree that D is the incorrect answer because the epidermis is sloughed off.
