The determination of death is basically based on the three principles of cardiac arrest, respiratory arrest, and pupil dilation. After the breathing stops and the brain waves stop, the heart will continue to beat. Even after the heart stops, the muscles will work for a few hours, and the gastrointestinal tract will continue to digest. The human cells can survive after the heart stops. 30 hours.
The toughest cells are the sperm in the male seminal vesicles, and they survive for nearly three and a half days, even if the heart stops beating. In other words, if artificial insemination is performed during this time, it is possible to leave behind.
