Major calyx
Two or three minor calyces converge to form a major calyx. The major calyx, in the kidney, surrounds the apex of the renal pyramids. Urine formed in the kidney passes through a renal papilla at the apex into a minor calyx then into major calyx before passing through the renal pelvis into the ureter.
Peristalsis of the smooth muscle originating in pace-maker cells originating in the walls of the calyces propels urine through the renal pelvis and ureters to the bladder.
