Top 5 things that the integumentary system can do: -Protects your inside organs from falling out -Heals injuries -Keeps germs out -Helps you get out toxins when you sweat -Keeps your body temperature regular

Your skin contains two main layers. You have a thin outer layer called the epidermis and a thick inner layer called the dermis. Inside you epidermis new cells multiply then they push your old cells out. Your epidermis contains melanin which determines your skin color. Your dermis contains sweat glands. These help you get harmful substances out of your body. Your skin has a self healing system. When you get a wound, your skin heads to the rescue. When you have a deep wound your skin heals by forming a scar. Before a complete scar is created, your skin puts new fibers together to make scar tissue. Even though it doesn’t work as well as the original skin it keeps the germs out by creating a protective barrier. After the barrier is all healed, you get a scar.
