The minor calyx, in the kidney, surrounds the apex of the malpighian pyramids. Urine formed in the kidney passes through a papilla at the apex into the minor calyx then into the major calyx.

Peristalsis of the smooth muscle originating in pace-maker cells originating in the walls of the calyces propels urine through the pelvis and ureters to the bladder.
