Cells are able to divide very quickly to replace those that are old or have died. Nerve cells are the only ones that is extremely hard to replace. However, even nerve cells can sometimes grow new connection if the message paths become damaged. Dead and dying cells are removed by white blood cells into the bloodstream which actually eats them. The liver is also able to break down red blood cells, which are only able to survive for a very short period of time. The cells’s control area, the nucleus, contains all the information and instructions to keep the cells alive and functioning.
