When it’s cold, your skin helps to keep you warm. When it’s hot, your skin starts to sweat to help keep you cool.
When you cut your skin, it can heal itself. First, your blood comes out and makes a hard layer called a scab. Then, new skin grows underneath. This skin might be a different colour and is called a scar.
