What are kidneys and what do they do?

You have two kidneys that are incredible organs that work quietly in the background to keep you healthy. Their main job is to filter and clean your blood. Your kidneys are full of tiny blood vessels and this is where all the filtering and cleaning happens. So, think of them a bit like a coffee filter, they are designed to filter the good stuff from the waste. 

All the good stuff your body reabsorbs and the waste, toxins and extra water, your kidneys filter leave your body as urine. This helps keep your body clean and balanced. 

Your kidneys also play a vital role in: 

• Controlling your blood pressure.
• Helping your body make red blood cells.
• Keeping your bones strong and healthy. Balancing important minerals, like sodium and potassium.
• Maintaining the right level of acidity in your blood.
