The individual units of the kidney, called nephrons, produce urine and empty into structures called collecting ducts. Many nephrons empty into a single collecting duct. Similarly, many collecting ducts empty into a minor calyx. Minor calyces empty into a major calyx, and the major calyces empty into the singular renal pelvis (each kidney has a single pelvis). The renal pelvis empties into the ureter.

Renal cortex
Cortex- outer kidney region that is composed of glomeruli, Bowman's capsule and proximal/distal convoluted tubules Medulla- inner kidney region that is composed of collecting ducts and the Loops of Henle Pyramids-con-shaped areas of the medulla; contains the Loops of Henle and the collecting ducts Pelvis- expanded upper end of the ureter; the kidney branches called calyces open into it Calyx- receives urine from the collecting ducts and directs the urine into the pelvis Capsule- connective tissue covering of the kidney
i think it is called the North Central Region because it is located in the North Central. :)
The central region of an atom is called the nucleus. The nucleus consists of many neutrons and protons which can form bonds.
Minor calyx
The central region of the sun is called the core.

The renal cortex is the outer region of the kidney. The medulla is the inner region of the kidney.
Someone left a foolish answer here, and the question is unnecessary and poorly-defined, too.
The renal cortex is the outermost, or most superficial, region of the kidney.
