Kidney Functions

■ Remove toxic wastes from the blood
■ Maintain body’s water content

When the Kidneys Don’t Work
■ Waste products in blood are not filtered out
– Too much phosphorus in blood – weaken bones
– Too much potassium – heart attacks
– Too much sodium – worsen high BP
– Too much water – swelling & difficulty breathing

If Kidney Damage…
