Apoptosis is the body's normal process of cell destruction. Necrosis on the other hand is abnormal and is caused by genetic defects or mechanical injury. Unlike apoptosis, the necrotic process involves cell swelling and damaging cell organelles. Eventually, the cell erupts, spilling out the cell contents into the blood stream. This causes inflammation and other types of immunological affects that could lead to diseases and conditions. Apoptosis slowly shrinks the cell and its remnants undergo phagocytosis.
