the body's acid/alkaline nature and the concentrations of salts,
minerals and other materials. The blood is filtered, purified,
cleansed and adjusted twenty-four hours every day. Hundreds of
pints of blood flow through these organs daily, about one-fourth
of the heart's output or approximately the body's entire volume.
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.
