How does death occur?

What is the difference between brain death and death?
In medical terms, there are two ways that death is determined. The most common and accepted form of death is cardiac death—the absence of the heart contracting and pumping blood due to a disturbance in its electrical activity. A less common type of death is brain death—the irreversible absence of all brain activity.

Can a dead person cry?
After death, there may still be a few shudders or movements of the arms or legs. There could even be an uncontrolled cry because of muscle movement in the voice box. Sometimes there will be a release of urine or stool, but usually only a small amount since so little has probably been eaten in the last days of life.
Why brain death is irreversible?
Mechanical support (a breathing machine) keeps oxygen going to the organs until they can be recovered for transplant. The machine is not keeping the patient alive (brain death is irreversible and is legally and medically recognized as death), it is merely keeping the organs viable until they can be recovered.
What happens immediately after death?
After death, the cells are depleted of their energy source and the protein filaments become locked in place. This causes the muscles to become rigid and locks the joints. During these early stages, the cadaveric ecosystem consists mostly of the bacteria that live in and on the living human body.
