The blood is filtered, purified, cleansed and adjusted twenty-four hours every day.

The blood circulates through the kidneys twenty times each hour for purification. About two and one-half pints of this flow becomes urine, although the amount largely depends on our consumption of food and drink, our physical activity and other factors.
