Summary Introduction
To review:
The similarities and differences between the apoptosis and necrosis.
Introduction:
Each and every cell present in the body undergoes cellular division giving rise to daughter cells. Once the cell ages, it enters the death phase and finally dies. Usually, it is natural, but sometime external factors are also responsible for the cell death. Apoptosis is a type of cell death that is usually triggered by a normal, healthy and programmed process of autonomous cellular dismantling. Necrosis is described as a premature death of the cell caused by some external factors like infection, toxins or any stress.
