8. The ureter is lined with transitional epithelium. The surrounding lamina propria and folded lumen allow for easy expansion of the lumen when necessary. The bladder has transitional epithelium and a thick lamina propria to allow for expansion. Red blood in, yellow urine out. The afferent arteriole is seen entering the glomerulus at the vascular pole (red arrows). The urinary pole (yellow arrow) is where the filtrate enters the tubule system (specifically, it enters the proximal convoluted tubule).
