What caused every human death?

Unlike general beliefs, human death is a process rather than a unique event. We often attribute the cause of human death a state or illness or trauma, but in fact the final cause of any human death is a state called cerebral hypoxia or cerebral ischemia . Simply put, all human death was a direct consequence of the deprivation of oxygen to brain cells. When doctors speak of the causes of human death, they often refer to the conditions that have led to the deprivation of oxygen. The causes of human death are often listed in the specific order of events. The cause of cancer patient's death may be listed as a cerebral hypoxy caused by lung edema caused by ubiquitous lung cancer. It may be acceptable to say that the death of the patient was caused by cancer or heart disease or severe trauma, but real human death is caused by the complication of these conditions.

fThe Unction of the circulatory and respiratory system of the body is to supply fresh oxygen and nutrient intake to all cells, but the brain is a particularly necessary organ. The brain requires almost a full 25% of the blood blood supply to function normally. When the disease threatens the ability of blood to supply oxygen, the body begins to prefer which organs receive the remaining healthy cells. As the disease progresses, the brain is often the last main organ except the heart that felt the effects of compromised blood cells.

and human death caused by sudden trauma is the case of brain hypoxia. Loss of blood caused by a shot or wound with a knife reduces the amount of oxygen reaching the brain. If this correct balance is not restored, the heart and lungs may fail and the brain literally starts choking. Many minutes of total oxygen deprivation, the brain may not be able to restore any meaningful function. The autonomic system controlling the heart and lungs fails, leading to the final cause of all human death - deprivation of oxygen of brain cells.
