The urinary tract is a system in the body that helps remove waste and excess fluids. It includes the kidneys, which filter blood to create urine, and the ureters, tubes that carry urine from the kidneys to the bladder. The bladder stores urine until it is ready to be expelled from the body. When you need to urinate, the urine travels from the bladder through the urethra, the final part of the urinary tract. This process is essential for maintaining the body's balance of fluids and electrolytes, ensuring that harmful substances are eliminated efficiently.
