Detailed explanation-1: -Portions of the renal cortex extend into the spaces between adjacent pyramids to form renal columns. The cortex and medulla make up the parenchyma, or functional tissue, of the kidney. The central region of the kidney contains the renal pelvis, which is located in the renal sinus, and is continuous with the ureter.
Detailed explanation-2: -The renal column (or Bertin column, or column of Bertin) is a medullary extension of the renal cortex in between the renal pyramids. It allows the cortex to be better anchored. Each column consists of lines of blood vessels and urinary tubes and a fibrous material.
Detailed explanation-3: -The renal medulla is the smooth, inner tissue of the kidney. It contains the loop of Henle as well as renal pyramids.
