The urinary system helps maintain homeostasis by regulating water balance and by removing harmful substances from the blood. The ureters, urethra, and urinary bladder complete this intricate system. Your kidneys, which are the main part of the urinary system, are made up of millions of nephrons that act as individual filtering units and are complex structures themselves. Understanding how the urinary system helps maintain homeostasis by removing harmful substances from the blood and regulating water balance in the body is an important part of physiology.
