THE KIDNEY

 

The RENAL COLUMN (or Bertin column, or column of Bertin) is a extension of the renal cortex into the medullary region 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.

The inner part of the kidney is composed of the RENAL MEDULLA.
