Because heart pumps oxygenated blood to the various parts of the body. When the heart stops beating the body does not get its dose of oxygen.

.The blood carries oxygen and nutrients to the cells of the body. The heart functions to pump the blood to the cells, so when the heart stops beating , the blood cant reach the cells and the cells eventually die due to lack of oxygen and nutrients. Thus a man dies when the heart stops beating.

First off a person does not always die when their heart stops beating as their heart can be restarted (what defibrilators are for). But if it cannot be restarted blood stops being pumped through the body, so it cannot provide the body with O2 (oxygen). The body needs oxygen to function, so when a person's heart stops they die.

The heart pumps blood and oxygen to the rest of the body. I assume it would take a few minutes for the brain to actually die.

Once the heart stops beating. oxygen is cut off from the rest of our organs, including our brain. If it is cut off for more than a few minutes, the brain dies, and so does the rest of us..

Blood is not pumped to the rest of the organs, especially to the lungs and the brain. All oxygen is turned into carbon dioxide and there is not enough for further respiration of cells. Since no respiration occurs, no energy is released and the man is just..a dead machine.

heart pumps blood throughout the body which carries oxygen to all the organs including the brains, which really needs oxygen to to stay functional. so if ur organs stop working, U DIE!!!!!

Because blood supply stops to all vital organs viz.,Brain,kidneys,lungs.liver and even Heart itself when the Heart stops beating.But modern science will nor recognize this as death since this can be treated or even Heart it self canbe transplanted with another healthy Heart .

...b/c the when the heart stops beating, the blood circulation to other vital organs in the body stops...leading to death of the cells and tissues...esp the brain. This eventually leads to death of the individual.

Man does not necessarly die when his heart stops beating. That's why we have cpr. Man does die when he/she does not recieve oxygen to the brain. That is the only cause of death.
