Yes. When the Aztecs sacrificed people, they cut out the heart and held it beating, to the sun.
No, a heart cannot beat outside of the body because it requires the body's systems and support to function properly.
A heart can typically beat outside the body for about 4-6 hours before it becomes nonviable.

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.
To pump blood through the body
Yes it does
The heart itself tells the heart to beat. It contains a small cluster of nerves that act as a biological "pacemaker".
An insect's heart is a tube-like structure that runs along the insect's back and pulsates to pump hemolymph (insect blood) through its body. Contractions of muscles surrounding the heart cause it to beat and circulate nutrient-rich hemolymph to the insect's tissues.
