The kidneys are amazing organs, vital to your survival. They are two bean-shaped organs the size of a human fist. They are located on either side of the backbone, just below the ribcage and they work around the clock to keep the body healthy. In fact, the kidneys are so committed to their role that someone who experiences kidney failure may experience no symptoms until the kidneys are working at less than 25 per cent of their capacity. The kidneys are a sophisticated waste removal system. They receive up to 200 litres (10 buckets or one drum) of blood through and around a million functioning units known as “nephrons”. As blood passes through the kidneys and around the nephrons, it is “cleaned” and the body’s waste products and excess fluid are removed according to the body’s needs. These waste products, along with the excess fluid, are then sent through the ureters to the bladder. Then they are passed out of the body as urine. In this way, the kidneys perform a range of vital functions: 1. Removing waste from the blood 2. Balancing the body’s fluid levels 3. Helping to control blood pressure 4. Stimulate the production of red blood cells 5. Maintaining strong, healthy bones.
