All that lives must die. What kind of process of death that will be experienced by every living creature?
It is not easy to predict exactly when a person will die. Death itself could have caused illness, accidents or other causes.
In normal conditions, such as the sick person will usually show symptoms that indicate that his life would soon end a few weeks longer as quoted from Mayoclinic, namely:
1. feeling restless.
A person will feel uneasy and sleeplessness, he will often change position during sleep due to feeling restless.
2. Pull away.
Someone does not want to again engage in social activities or do his favorite activity.
3. Often sleepy.
Someone will spend more time to sleep.
4. Loss of appetite.
Someone is just going to eat and drink in a little amount and different from the usual.
5. Experienced a lull while breathing.
This usually happens when a person is asleep or awake.
6. Luka which is difficult to heal.
Luka or infection experienced difficulties to be healed.
7. The swelling.
Swelling in some people in the hands, feet or other body parts.
The process of dying starts to happen when the body can't get oxygen intake is necessary to survive. Different cells have different death rate, so the length of a person's dying process depends on cells that lack of oxygen is.
While the brain requires oxygen in large numbers and have little oxygen reserves. So if the intake of oxygen is reduced then it will lead to cell death in 3-7 minutes.
Some signs demonstrated by the dying is a lot more sleep, this is to save the energy stay left little in the body. When that energy is lost, then someone will lose their appetite for eating or drinking. The process of swallowing becomes difficult and the mouth will be very dry, thus forcing the dying for a drink would make him choke.
In addition the dying would lose control of his bowels and bladder, so often looks incontinent. People will feel confused, anxious and not quiet because it cannot breathe with the regular. When cells in the body begin to lose the connection, then it will experience a muscle spasm.
The death would be closer if the feet and hands feel cold and turn blue due to getting a little a cessation of blood flow to the area. But in time will be increasingly spread to the upper parts of the body such as the arms, lips and nails. In addition to that person becomes unresponsive, although his eyes are open but has a gaze blank or don't see her.
After that breathing stops altogether and is followed by the stopping of the heart's work, then that person is clinically dead because there is no circulation and reserve oxygen to reach the cells in the body. However the clinical death can be reversed through a process of CPR (sigh of relief), transfusion or ventilator. But if 4-6 minutes after clinical death is no change, then it means that the heart is not able to work anymore.
Because the heart is not working, then automatically the flow of blood and oxygen throughout the body and the brain will also be halted. Due to the lack of intake of oxygen and blood to the brain, then within a few seconds the brain dead and there will also be the end of life of a human being.
