Urinary system: Bladder

The bladder has three layers of smooth muscle, and a transitional epithelium. It's harder to make out the three layers, because the bladder is sac like, not a tube.

The mucosa is heavily folded - this helps to accomodate for large volume changes.

The transitional epithelial lining can stretch until it looks like stratified squamous epithelium.
