what is the difference between apoptosis and necrosis? What triggers each process?

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.
