I ll post this in bio section too
Its seen that a turtles heart beats even after its stripped out from its body
But i need a physics view on this.. What gives the heart the energy to pump? Chemical energy?!

Nice.

anonymous · Answer

so its chemical energy huh!.. interesting.. so it gets converted into electrical impulses that make the heart pump?

anonymous · Answer

Wondering why it would pump even after getting stripped from the body!

anonymous · Answer

To simply put it... Yes, it's the chemical energy but as you and I know, there is always a complicated physical view on this :)

Stunning natural world we live.

anonymous · Answer

There is left over electrical current flowing which causes muscle constriction.  If you apply a current to a removed cow heart several days after removal it will beat.
