Question

why human heart remains functional even after death

Answer 1

Most muscles contract via electrical impulses from the brain. Then obviously they would cease to function if they were disconnected from the brain.


       However, the heart follows a pattern different than most muscles in the body.  The beating of the heart itself is not regulated by the brain, but actually within the heart itself. The only function of the brain is tell the heart how fast it needs to beat.  Nerve cells within the heart continue firing for an extended period of time, promoting the process of beating.
For this reason, a heart that is removed from the body doesn't stop beating instantly.  As long as it has enough ATP to provide energy and exposure to oxygen, it can beat without any regulation from a brain.
