Biological Process of Death
Death occurs when vital body functions permanently stop. This includes the heart, lungs, and brain. Without oxygen, cells begin to die, leading to irreversible loss of consciousness and bodily shutdown.
Common Medical Causes
People die from various medical conditions. Heart disease, cancer, stroke, and chronic respiratory diseases are leading causes worldwide. These conditions can disrupt blood flow, breathing, or brain function.
Other Factors and External Causes
Accidents, injuries, and infections also cause death. Severe trauma, drowning, or poisoning can be fatal quickly. Organ failure from infections like sepsis is another significant medical cause.
Understanding these causes helps in prevention and medical response. For detailed statistics, see the World Health Organization fact sheet on causes of death.
