Death for many people can be a taboo topic, even very difficult to say because evokes feelings of fear mysterious. In fact, finding out what happens to the body after death is not scary as you think.
Not just when cardiac arrest is viewed as leaving earth. To determine whether a person has actually died or not, doctors have to rely on a variety of symptoms combined. The first clear sign is the apnea and no longer respond to stimulation verbal or pain, eye pupil will not move and become dilated.
Here are the changes after death often classified according to the time frame and the decay of the body.
State body after death according to the time
Many studies show that the change occurred after death is most easily categorized based on the time frame within 1 hour, 2-6 hours, 7-12 hours and then 12 hours.
1, After the dead 1 hour
after death, all the muscles in the body will be in a relaxed state, entered the stage called primary soft dough. Eyelids began to lose tension, dilated pupils, jaw open, the joints and limbs become loose. When muscles no longer stretch, the skin will start to sag causing the joints and bones as jaw or hip more apparent.
A few minutes after the heart stops, pallor mortis phenomenon happens, that is normal ruddy color turns pale color. The reason is that there is less blood hemoglobin because uneven allocation.
Meanwhile, normal body temperature at 37 ° C will be reduced until the temperature of the surrounding environment. Phenomenon hypothermia after death only occurs when the ambient temperature is lower than body temperature at the time of death. Accordingly, the temperature will drop 2 ° relative C for 1 hour and further first reduced by 1 ° C per hour after that. Through this process, the forensic experts can determine the period of time of death of a person.
Because the ring is opened or closed due to brain control, so when the brain is no longer active, the system also inactivated sphincter. If the colon is still waste, or if you eat before death, sphincter system then no longer under the control of another brain should push the waste out of the body.
Movies are outstanding issues in newspapers and media over the past time due to the launch of a series of productions from Hollywood’s biggest movie producers. Let’s take a look at those works and give our opinions at FMovies
2, After the death of 2-6 hours
When heart stops beating and pumping blood incapable again, gravity will pull the red blood cells into the lowest part of the body. Blood clot causing the purple streaks, often called the blood pool or stain that inimitable corpse corpse.
Starting around now 3rd after death, the chemical changes in the cells causes the muscles begin to harden, leading to rigor mortis. Then, the first affected will be the eyelids, jaw and neck. Where the dying opened his eyes, contractures occur in eyelids will make the eyelid hold wide open eyes and cause not blindly death.
Many hours later, the spasticity will spread to the surface and down to the chest, abdomen, arms, legs until the fingers and leg cramps. Infants and young children when they die can not undergo rigor mortis phenomenon due to the smaller muscle mass.
3, Once died 7-12 hours
maximum time to complete the body cramps usually occur within 12 hours. However, this also varies depending on age, condition, sex, environmental temperature and other factors. This time will be very difficult to move the deceased’s hands, knees and elbows slightly bent, while the fingers or toes were crooked unusual.
4, After the death of 12 hours or more
After reaching state completely rigid, the muscles start to relax because of the chemical changes taking place in the cells and tissue decomposition inside. Secondary soft dough stage will occur next and lasts about 1-3 days. This process is influenced by many different factors, including temperature, such as low temperatures will make soft dough stage secondary slowed.
In the secondary phase brain soft, skin will start to shrink, creating the illusion that hair and nails are still developing but actually is not. Rigor mortis phenomenon will then take place in the opposite direction: from the fingers, toes to the face for about 48 hours.
