The two basic tissues of which the skin is composed are dense connective tissue, which makes up the dermis, and __1__, which forms the epidermis. Most cells of the epidermis are __2__. The protein __3__ makes the dermis tough and leather like.
The skin is made up of two main layers. The epidermis on the outside and the dermis underneath. New cells are made in the deep layers of the epidermis and are pushed towards the surface. The surface layers of the skin are made up of cells that have died and become filled with a substance called keratin.
