Biology Reading around the subject
...
I found out this process is called apoptosis and cells do
this if a cell becomes damaged or infected
...
Apoptosis is one of two ways cells can die
...
It's what happens to heart
cells during a heart attack, cells in severely frostbitten fingers and toes, and lung cells undergoing a
bout of pneumonia
...
As apoptosis destroys unwanted cells, mitosis (cell division) makes new cells
...
For example, our skin and hair cells are renewed via a continuous
cycle of apoptosis and mitosis
...
It then separates itself from its
neighbours, and unleashes the poisons
...
Within a
few hours, the cell shrinks, breaks up and is engulfed by other cells
...
In contrast with
apoptosis, clean-up of cell debris by phagocytes of the immune system is generally more difficult, as
the death generally does not send cell signals which tell nearby phagocytes to engulf the dying cell
...
There are many causes of
necrosis including injury, infection, cancer, infarction and others
...
Phagocytes are cells that protect the body by ingesting harmful
foreign particles, bacteria, and dead or dying cells
