Why do our cells shut down?

Some of the cells in the body get worn out and need o be replaced, like red blood cells. Other parts of the body don't wear out and dot need parts of the liver and brain. If the cells of these organs were not shut off from making more cells eventually the liver and brain would get bigger and bigger and your good cells would lose their happy homes. So our wonderful bodies know when to make and get rid of cells.
