urinary system
Body's liquid filter
The urinary system is the organs that produce and eliminate urine from the body—the kidneys, ureters, bladder, and urethra.
The kidneys filter waste from the blood; the bladder stores urine until it's expelled.
Also called the urinary tract, though that term more often appears in medical contexts like urinary tract infection.
