How Does Man lives 555 days without a heart Work?

Man lives 555 days without a heart by using machines that do what a heart usually does.

Normally, your heart pumps blood around your body, like a little engine in your chest. But if you don't have a heart, someone can help you with special machines that do the job instead.

These machines are connected to your body through tubes and wires, kind of like a water hose from a garden. One part of the machine pumps blood out, just like how a water hose sends water to your plants. Another part helps bring the blood back in, it's like having a bucket that carries the water back to the hose.

These machines work all day and night, so you can play, eat, and sleep without worrying about your heart. That’s why Man could live for 555 days, because his body had help from these cool machines doing what a heart usually does!
