what happens to the cells of injured tissue

Answer 1

cell get damaged ,sometimes it die ,and try to recover the damages

Answer 2

The cells of an injured tissue undergo a process called necrosis or apoptosis.  

        Apoptosis is termed as programmed cell death whereas, necrosis means sudden death.

       In the process of apoptosis, the cells undergo death in a programmed fashion which involves steps such as Cell shrinkage, nuclear fragmentation, Cytoskeleton disruption and "formation of apoptotic bodies".  

       These apoptotic bodies are cleaned by lysosomes.

       In the case of necrosis, proper cleaning or recycling of the cellular components does nit take place leading to the formation of scar or sometimes a benign tumor-like formation.
