There are two or three minor calyces that converge to form the major calyx. The spicules containing the basal portion of the upper tentacular part of the polyp of some soft corals also called calice. 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.

Has roughly cuplike extensions called calyces within the kidneythese are cavities in which urine collects before it flows on into the urinary bladder. Consists of specialized cells of the walls of the afferent arteriole and distal convoluted tubules. In renal pyramid the papilla projects into a calyx.

The cortex projects into the kidney dividing the medulla into triangular shaped renal pyramids whose apices are surrounded by a minor calyx calices plural. A body part of the entoprocta from which tentacles arise and the mouth and anus are located. The calyces become charged with oil glands and yield a greater abundance of volatile oil.

This causes them to fire impulses which stimulate rhythmical contraction. The urine then continues from the minor calyx to the major calyx and passes through the renal pelvis in the ureter. Due to the renal rotation during development the posterior calyces are are usually oriented with their long axis pointing towards the brodels line hence puncture of posterior calyx will traverse this relatively avascular zone but in case of anterior calyceal puncture there is an increased risk of bleeding as more parenchyma is traversed to reach the calyx and also because of the reason that it wont traverse through the brodels line14.
