The heart can remain beating in a person that is brain dead because their heart is not connected to their brain. A person that is brain dead is not necessarily alive because their heart is still beating.
The adrenal medulla is the part of the brain that keeps the heart beating
Your heart supplies the blood to your brain, however even if your brain is "braindead", your heart can still stay beating. The brain relies on the heart but not as much vice versa. When a person dies from a gunshot wound to the head, the body dies and of course, the heart stops. Either way, no-one can live without one, the other or a substitution. They are both essential to survival.
Your wouldn't be beating for long without your brain keeping the beating at a rhythmic pace and anyway you'd be brain dead
Brain stem
the brain stem is small part of the brain and the most important one because it keeps you breathing,keep your heart beating and also keep food moving through your digestive system.
Both the brain and the heart is important. If there are no brain, the heart would not be able to work. And if there are no heart, the brain would not have enough blood to function.The heat keeps beating when the brain is dead but only for a few secs.. but when the heart quits beating you have with in 5 min be for the patients is dead. and with in that time doctors can shock you back to lifeSo i say the Brain is more important.the brain, because if the heart stops you might still live but if the brain stops then your dead
Not having a mind of their own or a brain, the lungs "feel" nothing. But they may sense the beating of the heart and react accordingly.
The bullet kills your brain, which controls your heart, and the heart stops beating.
The earliest citation of the full 'be still, my beating heart' comes from William Mountfort's Zelmane, 1705: "Ha! hold my Brain; be still my beating Heart."
Yes, but only for a short time. You can stay alive for 3 minutes after your heart stopped beating. 3 minutes is all you get. So live close to a hospital in case when you get old.:)
This is because being dead is defined as stoppage in the functioning of brain and it is not having any relation with the functioning of heart. If the heart stops beating then there is no supply of oxygen rich blood to the brain and hence the brain dies and henceforth the person is declared dead.
A suitable isotonic solution would keep a heart beating outside of the body. Additionally, charges can be inserted into the solution to keep the Sino-atrial node in constant functioning.
