List and describe the different categories of death


Death has been broken down into the following categories:
• Functional death. The end of all vital functions, such as heartbeat and respiration.
• Cellular death. The gradual death of body cells after the heart stops beating. If placed in a tissue culture or, as is the case with various organs, transplanted to another body, some cells can remain alive indefinitely.
• Death. The moment the heart stops beating.
• Brain death. The end of all brain activity, indicated by an absence of electrical activity (confirmed by an electroencephalogram [EEG]) and a lack of reflexes. The notion of brain death is bound up with what we consider to be the actual person, or self. The destruction of a person's brain means that his or her personality no longer exists; the lower brain centers controlling respiration and circulation no longer function.
• Spiritual death. The moment the soul, as defined by many religions, leaves the body.
