Böbrek, or kidney, is a vital organ in the human body responsible for filtering blood and removing waste products. Each person has two kidneys, located on either side of the spine, just below the rib cage. They play a crucial role in maintaining the body's fluid balance, regulating electrolytes, and producing hormones that help control blood pressure. In addition to waste removal, böbrek also helps in the production of urine, which is the body's way of excreting excess substances. The kidneys work continuously, ensuring that harmful toxins are eliminated while retaining essential nutrients. Proper kidney function is essential for overall health and well-being.
