Can a heart continue to beat outside the body?
The heart has its own electrical system that causes it to beat and pump blood. Because of this, the heart can continue to beat for a short time after brain death, or after being removed from the body. The heart will keep beating as long as it has oxygen.
How long can heart survive outside the body?

What happens if you stop breathing for 1 minute?
