EXCRETORY SYSTEM
Your kidneys filters your blood to remove waste. They're part of the excretory system.
Your kidneys separate the liquid waste (urine) and your blood.
Two tubes, called ureters, carry the waste from your kidneys to your bladder.
Your bladder holds the urine until you go to the toilet. When you go to the toilet, the urine leaves your body.
