No single organ stays "alive" indefinitely after death, but some tissues like skin, corneas, tendons, and heart valves can remain viable for hours or even days for donation, while some cell functions (like white blood cells) can last up to three days, far outliving the brain and heart which stop within minutes. Death is a gradual process, not an instant switch, with cells and tissues shutting down at different rates.
The brain and nerve cells require a constant supply of oxygen and will die within a few minutes, once you stop breathing. The next to go will be the heart, followed by the liver, then the kidneys and pancreas, which can last for about an hour. Skin, tendons, heart valves and corneas will still be alive after a day.
Touch and hearing are the last senses to go when we die.
The brain is generally considered the last major organ to die, with electrical activity continuing for minutes after the heart stops, but specific cells like white blood cells can survive for days, and tissues like the cornea and skin remain viable even longer, highlighting that "death" is a process with different timelines for different tissues.
You shouldn't fear death because it's a natural, inevitable part of life, and accepting its impermanence helps you focus on living fully in the present, find peace by letting go of attachments, or find hope in spiritual beliefs about an afterlife, with philosophies suggesting it's just the end of experience, making the fear itself pointless. Many find liberation in understanding that all things change and by focusing on leaving a positive legacy, as suggested by existentialists.
The stages of death include: Pallor mortis: The main change that occurs is increased paleness because of the suspension of blood circulation. This is the first sign and occurs quickly, within 15-30 minutes of death.
For the first few minutes of the postmortem period, brain cells may survive. The heart can keep beating without its blood supply. A healthy liver continues breaking down alcohol. And if a technician strikes your thigh above the kneecap, your leg likely kicks, just as it did at your last reflex test with a physician.
The brain is the organ that cannot be donated for transplantation in humans. While multiple solid organs including kidneys, liver, lungs, and heart can be successfully transplanted from deceased donors, the brain itself is never procured or transplanted 1.
How long will I have to wait to receive a transplant?
People nearing death may report encounters with people who are already deceased or describe having been places or seen things not visible to others. These experiences, often referred to as visions or hallucinations, are not typically a drug reaction or mental illness.
The Catholic conception of the afterlife teaches that after the body dies, the soul is judged, the righteous and free of sin enter Heaven. However, those who die in unrepented mortal sin go to hell.
For many people, dying is peaceful. The person may not always recognise others and may lapse in and out of consciousness.
For most people, the terror of the actual process of dying probably involves a fear of physical pain. It also probably involves fearful incomprehension of the seemingly mysterious process by which the consciousness that is our "self" is extinguished, or fades away.
Where people go after death is a profound question with answers rooted in religion, philosophy, and personal belief, ranging from an eternal spiritual afterlife (Heaven, Hell, or spiritual realms) or rebirth (reincarnation) to the cessation of consciousness, with no single universally accepted destination, though many faiths offer specific paths like Islamic belief in Al-Barzakh or the Hindu concept of Karma.
It takes around 12 hours for a human body to be cool to the touch and 24 hours to cool to the core. Rigor mortis commences after three hours and lasts until 36 hours after death.
Some organs, like the brain, cannot be transplanted. Tissues include bones, tendons (both referred to as musculoskeletal grafts), cornea, skin, heart valves, nerves and veins. Worldwide, the kidneys are the most commonly transplanted organs, followed by the liver and then the heart.
The earthly body will not enter into the heavenly inheritance (1 Corinthians 15:50). Based on these facts, there can be no justification for prohibiting organ donation and transplantation because of the need for a physically intact body prior to entering the resurrected state.
The “Dead Donor Rule” (DDR) lies at the heart of current organ procurement policy. [10] It is not a legal statute; rather, it reflects the widely held belief that it is wrong to kill one person to save the life of another. On those grounds, an organ donor must already be dead before vital organs are removed.
A conscious dying person can know if they are on the verge of dying. Some feel immense pain for hours before dying, while others die in seconds. This awareness of approaching death is most pronounced in people with terminal conditions such as cancer.
- *Hinduism*: Some Hindu texts suggest the spirit may linger near the body for up to 13 days after death. Scientific Perspective From a scientific standpoint, there's no empirical evidence to support the idea that the spirit or consciousness remains in the body after death.
Rather, patients speak of relationships with the people they love and who love them; what life means to them and how they might be remembered; the reality of death; their hope that they won't be a burden to others; their worry about how those they are leaving behind will manage without them; and a fear of the process ...
Final stage (minutes before death).
In the last minutes of life, breathing becomes shallow and may stop altogether. The heartbeat slows and eventually ceases. The body may make reflexive movements, such as small twitches, but these are not signs of pain or distress.
Both terms essentially mean "examination after death." Why is the tongue removed during autopsy? The tongue is removed during autopsy to thoroughly examine the oral cavity, access other throat structures, document any abnormalities, take tissue samples for further examination, and eliminate obstruction.
Black putrefaction (10-20 days after death) – exposed skin turns black, bloating collapses and fluids are released from the body. Butyric fermentation (20-50 days after death) – the remaining flesh is removed, butyric acid is formed "fermenting" the remains and the body begins to mold if in contact with the ground.
