Q | what is the bladder?
A | The bladder is the organ that sits within the bony pelvis connected to the kidneys above via the ureters and the urethra below. It is a hollow organ and acts as a reservoir for urine produced by the kidneys.
When the bladder contracts, the urine is expelled via a sphincter mechanism, down the urethra and out of the body. The outer wall of the bladder is formed by a meshwork of muscle fibres arranged in layers.
The inner wall of the bladder has a special lining called transitional epithelium, which is resistant to urine absorption.
