Minor Calyx of Kidney The structure indicated is the minor calyx of the kidney. The kidney consists of an outer cortex and an inner medulla. The cortex projects into the kidney dividing the medulla into triangular shaped renal pyramids, whose apices are surrounded by a minor calyx (calices = plural). The minor calices join to form a major calyx, which in turn unite to form the renal pelvis which exit the kidney to form the ureters. The calyx system of the kidney serves to drain urine.

Renal Pelvis

Renal Pelvis The renal pelvis is the proximal dilated aspect of the ureter in the kidney. It functions to funnel urine into the ureters.

To learn more about the internal anatomy of the renal pelvis take a look at this video.
