Two or three minor calyces converge to form a major calyx. A 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 a 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.
