The kidneys and bladder are two organs that get rid of urine.
Explanation:
The kidneys waste from the blood and produce urine. There are two thin tubes that carry the urine from the kidneys to the bladder. The bladder is like a bag that holds and stores the urine.
The kidneys make urine by filtering wastes and extra water from blood. Urine travels from the kidneys through two thin tubes called ureters and fills the bladder. When the bladder is full, a person urinates through the urethra to eliminate the waste.
