What organs make up the urinary system and how do they work together to maintain proper function?

The organs of the urinary system include the kidneys, ureters, bladder, and urethra. The kidneys filter waste and excess fluids from the blood to produce urine. The ureters carry urine from the kidneys to the bladder. The bladder stores urine until it is expelled through the urethra. Together, these organs work to remove waste and regulate the body's fluid balance to maintain proper function.
