The Insight Corner Hub: Physiological Death vs Human Death

Physiological death and human death are two terms that are often used in medical and philosophical discussions about the end of life. While they may seem similar, they refer to different aspects of the dying process.

Physiological Death

Physiological death is defined as the complete cessation of all vital organs¹. This differs from the broader definition of death, which is typically recognized when respiration and cardiac functions cease¹. At death, the pupils become fixed and dilated, and the skin on the face and extremities becomes cool to the touch¹. 

Physiological death is not as clear-cut as the conventional definition of death as many physiological processes of the body can continue after cessation of respiratory, cardiac, and brain functions¹. It is therefore debated whether a person is actually dead when brain function has ceased, but life support maintains the body’s vital functions¹. Some believe the absence of brain activity is conclusive evidence of death, with the body’s “machinery” simply continuing as normal, but with nobody at the wheel¹. Others argue that a person cannot be considered dead until all physiological functions of the body cease – physiological death¹.

Human Death

Human death, on the other hand, refers to the total cessation of life processes that eventually occurs in all living organisms⁴. The state of human death has always been obscured by mystery and superstition, and its precise definition remains controversial, differing according to culture and legal systems⁴.

According to Merriam-Webster, human death is defined as "the irreversible cessation of all vital functions especially as indicated by permanent stoppage of the heart, respiration, and brain activity: the end of life"⁶.

Conclusion

In conclusion, while both physiological death and human death refer to the end of life, they focus on different aspects. Physiological death refers to the cessation of all vital organ functions, while human death refers to the total cessation of life processes. The definitions of both terms can vary based on cultural, legal, and medical perspectives. Understanding these differences can help provide a more nuanced understanding of death and dying.
