The primary purpose of the urinary system is to regulate the body’s fluid balance and remove waste products from the bloodstream. This system includes the kidneys, ureters, bladder, and urethra. The kidneys filter blood, extracting nutrients and reabsorbing water, while excreting excess substances as urine. By maintaining electrolyte levels and regulating blood pressure, the urinary system is vital for homeostasis. Additionally, it plays a role in the elimination of metabolic waste, toxins, and excess minerals, ensuring overall health.
