Conclusion:

An artificial heart is a fake heart that doctors put in your body when your old heart doesn't work that well. I found out that the jarvik artificial heart was created by Robert Jarvik, and the regular artificial heart was designed by Dr. Paul Winchell. They are inserted by cardiologists, and the hearts are made out of metal, plastic, ceramic, and other animal parts, such as the pig. The valves are a pig’s valve (because our body is most like a pig’s).

They are powered by an external battery pack that is clipped on the outside of someone who has an artificial heart inside their body. The battery pack is connected to the wireless energy transfer system, which connects to the artificial heart so it can always be powered. There is an internal rechargeable battery so the external battery pack won’t run out of power.

They are good for people, but dangerous, because when the doctors are inserting it, they might accidentally make a mistake and kill the person. They help a lot, because if someone’s heart has a problem, or stopped running, someone rushes them to the hospital, and they get an artificial heart inserted into their body so they can stay alive.
