Best Answer

If the body does not get rid of the waste material, it will accumulate in the body where it is no longer needed. This waste material, when accumulated in the blood and other parts of the body , can become harmful. This happens when the kidneys and liver stop working or the large intestines no longer function properly, and it can lead to death.
