The bladder is a hollow organ that holds urine. The kidneys produce urine and send it to the bladder thru two tubes ( the left and right ureters) As urine collects in the bladder, the bladder enlarges like a balloon. When the bladder reaches a certain level of fullness it triggers your urge to void. Normally you are able to suppress this urge until you can reach the bathroom. When you are ready to urinate, the urine travels from the bladder through the urethra. The urethra is a small tube that goes from the bladder to the outside of the body.
