Artificial organ

An artificial organ is something that is made by scientists and doctors that works like a real organ in the body. Sometimes people's organs don't work correctly and need to be replaced, so doctors make a fake one that looks and works just like the real one. Artificial organs are made from different materials, like plastic or metal, and can be used to help the body do things like make blood or pump blood around.
