Why blood is not taken from the dead body?

Blood donors less than world demand. Accidents and other emergencies, including the need for blood is at the moment. Still bad, but the fact that the artificial blood is not made. Blood donation amount is less, then why are we not taking blood from the dead body? So people are constantly dying, dead people do not need the blood. If you have a shortage of blood from the blood of a dead body cannot be resolved? So many of them posthumously eyes, kidneys and other organs are donated, so the blood cannot be given, why? In fact, it is easy to hear, but the collection of blood from the body of the dead are some complications.

After the death of the body, blood is lost quickly. With the closing activity of the body, the accumulation of impurities in the blood. Among pollutants are carbon dioxide, lactic acid and other substances. They are alive and are processed through the kidneys and lungs. Blood alkaline levels (pH) are changed from the normal state. Blood clot broke out. Several deadly germs can breed rapidly. Of course, it will depend on a person had died. After the death of someone who died of any disease, such as bacterial microbe that can be quickly covered with the blood. The inner body's immune system to prevent or germs are not active.

As blood is lost so quickly after the death, the blood collected can be taken immediately. Theoretically, it can be used if the blood taken immediately. But here is the thing. Other organs of the body which is donated are more important than giving blood, to keep them suitable for use in the presence of blood. Before the need to take out, the presence of blood in the organs is required.

The question may be arise why the organs is more important than the blood? First of all, alive human can donate blood without any damage but can’t kidneys, eyes, lungs etc. Since people are living to donate blood, collect rare organs is better to using the blood of the dead man. Second, the blood is made with time. From a dead man the blood can be found only once, but by creating awareness about blood donation a man living the life of every 3/4 months after the blood can be collected. Considering all aspects, the blood of a dead body is not recommended.

The blood of the dead body donates to living body was first tested on dogs. The test showed, the blood collected from dead body insert into the living body within 6 hours was found nothing harmful. This test was done during the Soviet Union. But the dead man's blood insert to the living body is not supported including the United States and other countries have not yet.
