The Urinary System

The Urinary system takes bad things out of the blood and washes it out of the body. This liquid waste is called urine. Without the urinary system, poisons would fill up the blood and kill a person. The kidneys are organs that filter the blood and remove poison. Urine is stored in a bag called the bladder and it leaves the body through a tube called the urethra.
