What is the function of the kidneys?

• Filter the blood and get rid of waste products (every day our kidneys filter an average of 200 liters of blood – a quantity that would fill 20 buckets)
• They balance electrolytes such as potassium
• They secrete a hormone called Renin that regulates blood volume and blood pressure
• They secrete the hormone erythropoietin that helps with red blood cell production
• They have the key enzyme to activate vitamin D (that we get from sun exposure or diet)
