Condition in which brain no longer functions?
When the brain no longer functions, it is typically referred to as brain death. Brain death is the irreversible loss of all brain function, including the brainstem, and is considered the legal and medical criteria for death in most countries.
How are brain death and cardiac death different?
Brain death is the irreversible loss of all brain function, including the brain stem, resulting in the cessation of all neurological activity, whereas cardiac death is the irreversible stoppage of the heart, leading to the cessation of circulation and oxygen delivery to vital organs. Brain death is considered the legal and medical standard for determining death in many countries, while cardiac death is when the heart stops beating and cannot be restarted.
What is the boiling point of BRAIN?
The boiling point of the human brain is around 98.6°F (37°C). This is the normal body temperature at which the brain functions optimally. Boiling the brain would lead to irreversible damage and death.
Can Carbon monoxide poisoning kill you if you're already unconscious (by a drug or in anyway)?
Yes, carbon monoxide prevents incorporation of oxygen to erythrocytes causing irreversible brain damage and even death.
What is the difference between reversible and irreversible ischemia?
Reversible ischemia occurs when blood flow is temporarily restricted to an area, but the tissue is not permanently damaged and can recover if blood flow is restored quickly. Irreversible ischemia, on the other hand, results in permanent tissue damage due to prolonged lack of blood supply, leading to cell death and potentially organ dysfunction.
What is the meaning of brain death?
Brain death is the irreversible end of all brain activity. The term brain death should not be confused with a persistent vegetative state like many people tend to do.
Which medical school wrote the standard definition of death in 1968?
In 1968, Harvard Medical School defined death as irreversible damage to the brain, or brain death.

Brain death is considered the legal and medical standard for determining death in many countries, while cardiac death is when the heart stops beating and cannot be restarted.
What does the uniform determination of death act state?
An individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead. A determination of death must be made in accordance with accepted medical standards.
What organ death occurs when there is an absence of heartbeat with no chance of resurrection?
If there is an absence of a heartbeat with no chance of resurrection, it typically results in brain death. This means that the brain has permanently stopped functioning and cannot be revived, leading to the irreversible cessation of all brain activity.
Is brain death truly death?
Brain death is considered a legal and medical definition of death in many countries. It occurs when there is irreversible loss of all brain function, including activity of the brainstem. While the heart may still be beating with the help of life support, the individual is considered dead as there is no possibility of recovery.
Has anyone ever survived brain death?
No, brain death is defined as the complete and irreversible loss of all brain function, including the brainstem. Once a person is declared brain dead, they cannot recover consciousness or any brain activity. Some cases may involve misdiagnosis, where patients initially thought to be brain dead later show signs of life, but true brain death itself is permanent.
What are the spiraling events if the cardiovascular system fails?
If the cardiovascular system fails, oxygen ceases reaching the body cells, most notably the brain cells. Without fresh oxygen reaching the brain, cells begin to die. In four minutes, imminent death is irreversible, or at the very least irreversible without permanent brain damage.
How is death defined according to biology?
Death is the permanent and irreversible termination of all biological activity in a living organism, including the brain and the senses. When an organism is dead, it is deprived of the ability of self-movement.
Is Death reversible or irreversible?
death is reversible ?why? give scientific logic?
How does a gunshot to the brain kill you?
A gunshot to the brain can kill you by causing severe damage to vital areas that control essential functions such as breathing, heart rate, and consciousness. The impact and damage from the bullet can disrupt these functions, leading to immediate death or irreversible brain injury.
