Distinguish between cellular death and death of the organism
Cells can die but an organism can still be alive. But even when an organism is dead they can have cells that are still alive.
Cellular death refers to the death of individual cells within an organism, while death of the organism refers to the cessation of all bodily functions and the permanent loss of consciousness.
Cellular death can occur for a variety of reasons such as damage, injury, apoptosis, or necrosis. It may occur as a result of external factors like injury, exposure to toxic agents, or infection. Damage to cells can result in programmed cell death (apoptosis) which helps maintain the overall health of the organism. On the other hand, necrosis is an uncontrolled death of cells caused mostly by pathological factors which results in inflammatory responses in the surrounding area.
Death of the organism, on the other hand, is a complex process that involves the permanent loss of consciousness and the body’s inability to perform vital functions. This can be caused by a variety of natural or unnatural factors such as old age, disease, genetic or environmental factors, accidents, and trauma. The death of the organism is a significant event that has legal, medical, social, and psychological implications. It leads to the cessation of all vital signs including breathing, pulse, heart function, and brain activity.
Therefore, while cellular death refers to the death of individual cells within an organism, the death of the organism refers to the irreversible cessation of all vital functions and the permanent loss of consciousness.
