Question by Stuart C: What is the difference between necrosis and apoptosis?
Best answer:
Answer by Alone GuY
Cells die through either of two distinct processes: necrosis or apoptosis. Necrosis is death due to unexpected and accidental cell damage. A number of toxic chemical or physical events can cause necrosis: toxins, radiation, heat, trauma, lack of oxygen due the blockage of blood flow, etc.
Apoptosis is sometimes called programmed cell death.
Apoptosis originally referred to the process by which leaves falls from trees in the autumn, but it has been adapted to describe this type of non-traumatic cell death.
Apoptosis is a way to remove unwanted cells. During apoptosis, cellular contents are not released and inflammation does not occur.
The apoptotic cells are rapidly engulfed by their neighbors an removed.

for the sake of understanding, i will use simple words, necrosis is when a tissue gets infected/inflammed and hence rots, where as apoptosis is the natural way in which body dissolves/autodigests/does away with the tissue. Mmind you the later doesnot have the element of infection.
Necrosis refers to the death of a cell or living tissue due to external factors like infection or some kind of trauma. When compared to apoptosis, it can be considered “accidental or unintentional” death.
Apoptosis, on the other hand, is usually defined as programmed cell death, which occurs naturally at the end of a cell’s life to help the body rid itself of old or non-functional cells.
