The bladder is lined by an elastic stratified epithelium with cells that change shape according to the volume of urine currently stored. When the bladder is full, the pressure exerted by the urine compresses this tissue and the cells take on a thin, flat, squamous appearance (Figure 1.8G2). As the bladder empties, the cells become progressively less compressed, gradually adopting a cuboidal and then a columnar appearance (Figure 1.8G1).
