What happens to the blood when you die?

As the blood circulation in the body stops due to heart failure, the blood slowly begins to clot and collect at the lowest points of the body due to gravity. Corpse spots are formed. In patients lying on their backs, the back and back of the legs are particularly affected. The cadaveric lividity already develops in the first hours after death. The coagulated blood shows through protruding blue veins and is decomposed by bacteria during the decomposition process.

What happens in the brain when you die?

The brain is incredibly sensitive to changes in the oxygen concentration in the blood. It is therefore the first organ to be damaged after an oxygen deficiency due to heart failure. The time a brain can survive without oxygen supply is about 5 minutes.

After that, massive irreversible damage to nerve cells in all areas of the brain occurs. This time is therefore also the limit for the length of a resuscitation process. If the heart does not start beating again after this time, this can lead to brain death.

This is irreversible; from a clinical point of view, the patient is now dead. However, the affected person does not notice any of this, since a coma occurs shortly after the oxygen deficiency has occurred. Some patients who could be resuscitated by resuscitation report near-death experiences during heart failure. Whether these are based on biological processes or religious ideas cannot be determined.

What happens in the intestine when you die?

In a healthy person, continence is produced by the constant tension of certain ring muscles called pylori. These close, for example, the exit of the stomach, small intestine and rectum. After death, the brain sends no further signals to these ring muscles and they become flaccid.

As a result, death is often accompanied by bowel evacuation. After death, the bacteria that live in the intestine are significantly involved in the decomposition of the body.
