The bladder is where urine gets stored before going to the toilet. The bladder holds around 400 to 600ml or urine. Learn more bladder facts here:
The bladder is located in the pelvis above and behind the pubic bone. It is pear shaped, and about the same size as a pear when it is empty.
The kidneys make urine that travels down ureter tubes into the bladder.
Urine is stored in the bladder which stretches to take more liquid until a person is ready to go to the toilet.
When peeing, bladder muscles contract, and two sphincter valves are opened to let the urine out.
Urine leaves the bladder through the urethra. This tube is longer in men than women because of the additional length of the penis.
