The two ureters empty into the
bladder.
The ureters enter the bladder posteriorly at oblique angles, thereby preventing reflux of urine.
The bladder is also lined with a transitional epithelium. It also contains an extensive lamina propria and three layers of smooth muscle which run perpindicular to each other.
In this distended (filled) bladder,
two of the smooth muscle layers are evident, and the transitional epithelium looks like stratified squamous.
In an empty bladder, the epithelium appears much taller, and the many epithelial infoldings reflect the elasticity of this organ.
