A
Inside the kidney, there are two zones, an outer cortex (5) and an inner medulla. The medulla is divided into a few conical masses called medullary pyramids (1) projecting into the calyces (sing: calyx). The cortex extends in between the medullary pyramids as renal columns called Columns of Bertin.The renal calyces are the chambers of the kidney through which urine passes. The minor calyces (4) surround the apex of the renal pyramids.The point of each pyramid called the papilla (2), projects into a calyx. The cortex contains blood vessels and collecting duct.
