= = Billions of skin cells that weigh about seven pounds. Skins cells stack together like the plant cells it has tiny bricks to make protective “wall” around the body. The skin’s outer layer is called the epidermis, that layer is mostly dead skin cells. These dead cells flake off everyday. The dermis allows you to sweat, dermis means “ a thick layer of living tissue, below the epidermis that forms the true skin, containing blood capillaries, nerve ending, sweat gland, hair follicles and other structures”. The cells in the dermis keeps the skin soft and waterproof. Maintaining temperature many blood vessels run through the skin. When you become warm the amount of blood that flows through them increase. Changes allow heat to move from your body into waste s is materials that comes from the breakdown of chemicals during cellular processes also helping to eliminate waste.

In the outer layer that part is dead these cells make the skin waterproof because they contain a tough protein called keratin. These cells washes off when you take a bath or a shower. Another one is in the middle layer it contain substances that makes keratin. And also there is the bottom layer it makes new skin cells = =
