Yes. When the Aztecs sacrificed people, they cut out the heart and held it beating, to the sun.

Your entire body has a heart beat. The heart beat is your heart ... beating ... it is pumping blood to every part of your body. You just never paid attention to your body before evidently.
When a heart is outside the body, and the body dies.
Unless stopped by "outside forces" the heart will continue to beat on at a quick enough rate to force blood through the body. If that blood were to stop, even for a few seconds, the effects could be devastating. Blood makes possible many of the bodily processes necessary to live, including breathing. The heart without any disturbances of that "outside" nature (leave you to imagine what out of many possibilities could cause a heart to stop) will always beat on at a fast rate so that no part of the body goes without the very life essense of humans, blood.
The heart is connected to the body, it is an integral organ.
Yes it does
To pump blood through the body
The heart itself tells the heart to beat. It contains a small cluster of nerves that act as a biological "pacemaker".
Heart beat,peristalsis
Your brain controls your body it tells you and your body parts to do ,and when to do things such as your heart, it tells your heart when to beat and without your brain it wouldn't tell your heart when to beat so u would die.
Valves control the flow of blood. Without them blood could flow backwards.--------------------------Yes, true. Valve would maintain one way traffic for blood right from the heart and to outside parts of the body and form outside to the heart.
When you are working hard, it will beat faster to get oxygen to the body more quickly. When resting, it will beat more slowly.
