Your two kidneys have a very important job to do – they keep your blood clean!
As your blood travels round your body, it also picks up waste from other cells. Your kidneys turn the waste into wee (or urine) which you get rid of when you go to the toilet. The urine is stored in your bladder.
The muscles
around your bladder control the urine flowing in and out
When your bladder is full you will feel the need to go to the toilet.
Each kidney makes up to four cups of urine a day
