Answer
The primary part of the epidermis is skin cells which are flattened and hardened as they push to the surface. These flat, hard cells allow the skin to be waterproof, limiting water loss and helping the body maintain water homeostasis. The dermis is made up of dense but flexible collagen fibers. These fibers allow for flexibility without overstretching.
