Healthy
kidneys have several important functions, including the production of
urine. These functions are:
1. Healthy kidneys
maintain water balance by removing excess fluid from our body.
2. Healthy kidneys
remove waste products, There are many chemical reactions that take place
in our body to maintain life. This process is called metabolism.
Metabolism results in waste products that become toxic (poisonous) if
they are left to accumulate in our body. The healthy kidneys make sure
you keep the right amounts of these chemicals and get rid of those we
don't need.
3. Healthy kidneys
maintain normal blood chemistry. A number of chemicals such as
potassium, sodium, phosphorus, calcium, bicarbonate, magnesium and
chloride are important to our blood chemistry. Healthy kidneys make sure
we keep the right amounts of these chemicals and get rid of those we
don't need.
Besides,
kidneys also make three important hormones - renin, erythropoietin and
calcitriol:
-
Renin
helps increases blood pressure. If blood flow through the kidneys is
reduced, extra renin is released and may cause high blood pressure.
-
Erythropoietin helps maintain the right amount of blood in your body
(blood volume) by stimulating our bone marrow to make more red blood
cells. Too little erythropoietin causes anemia, making a person look
pale and feel weak.
-
Calcitriol help your body absorb calcium from the food we eat. Our
bones need calcium to stay strong and healthy.
