When a person dies?

Question

the heart cells are myogenic(they beat by their own) So, when a person dies what causes the heart to stop beating?

Answer 1

All cells require oxygen,when oxygen is denied,the cells start to die.Cardiac muscle also needs oxygen,therefore when the oxygen-co2 exchange is no longer possible,red blood cell,which are the only cells in the body able to carry oxygen,are loaded with co2,the body dies.Oxygen is the catalyst that allows sugar to give up its energy for cell function.When you run out of oxygen,suger can't be converted to energy and the cells die.

Answer 2

People are considered dead when the electrical activity in their brain ceases. When electrical pulses are not received from the brain, the heart will stop beating. Oxygen deprivation for roughly seven minutes is sufficient to kill the cerebral cortex. If the heart stops beating due to some other causes, the brain will not get oxygen and the brain death will also occur.

Answer 3

The lungs have stopped breathing which means there is no oxygen getting to the heart muscle to continue beating.

Answer 4

Myogenic or not, they require oxygen. Without oxygen, no organism can survive.

Answer 5

myocardium is an involuntary muscle and consumes oxygen, any pathological state resulting in depriving the heart of its oxygen supply can results in heart from beating e.g excessive bleeding, drowning, electrcal shock, shot in the brain etc.

Answer 6

Lack of oxygen to heart muscle.

Answer 7

no oxygen honey

Answer 8

when the heat stop its over.
