From Wikipedia, a free encyclopedia written in simple English for easy reading.
[edit] Urination
The bladder is an organ in the human body. All the liquids that we drink have to go through our bladder. The bladder takes in the liquid in order for your body to function. The bladder works together with the kidneys. The kidneys clean the liquid we drink and turn it in to liquid. this proses goes on till the bladder is too big to hold it in, sending a beat to the brain telling it to go to the toilet. Once this message is received to the brain, the bladder starts to contract and the muscles start to squeeze. At the same time the bladder sends a message to the support muscles (pelvic floor muscles) that around the outer muscle of the bladder to relax and let the liquid pass.
