The kidneys function as our body's cleaners. They filter harmful waste from the blood and excrete it along with water as urine. But they don't just clean up waste, they are also responsible for the production of the hormone erythropoietin, which makes our bones stronger. This hormone helps blood cells in the bone marrow to mature and thus protects the body against anemia. However, they also contribute to the synthesis of vitamin D, regulating the balance of calcium and phosphorus, which is critical for our bone health.
