ELI5: Do all organs/bodily processes cease immediately at death?

For example, does the body continue to digest or produce insulin for a period of time after the brain shuts down, using resdiual energy, or do they instantly shut down at the moment of death?

Furthermore, are there other factors that would change the answer, such as cause of death (electrocution vs. blunt force trauma for example) or environmental factors (such as extreme temperatures?)

Certain organs can continue to live for a short while after death. The heart and lungs are "living" for about 4-6 hours after death, the liver and pancreas are "living" for about 24 hours after death, the kidneys for about 72 hours. These are the windows where organ transplant is still viable. 

The manner of death is absolutely a factor. Electrocution basically "cooks" the body from within, so all of these organs are basically dead afterward. If you have a heart attack, all of these organs are immediately dead as well (except corneas, which are tissues and not organs). If you just get hit in the head by a baseball bat, your organs will continue to live for a while. Organs don't really need that much brain function to keep going. 

Environmental factors could change these time estimates; extreme cold can preserve organs for much longer, and the opposite is true for extreme heat.
