The integumentary system provides a waterproof layer to keep water inside the body. The integumentary system consists of the skin, hair, nails, glands, and nerves. Of these, it is the skin that protects the body from dehydration. The skin is waterproof because its outer layer contains a protein called keratin and glycolipids.
